[http://www.wimsbios.com/phpBB2/topic4046-15.html ShareDoc, Aug 15, 2003:]

I got rid of the memory stability problem by disabling the 32M PC66 memeory that is built in the motherboard. I found out that byte 2B of CMOS controls the SDRAM banks. Bit b0 disables internal 32M memory. By changing the content from 80 -> 81 the 32M is disabled.

Now I have two 128 Sodimms working fine. No need more to seek for cas3.

PostPosted: Tue Nov 28, 2006 2:17 pm Post subject: Reply with quote
Some 600E and 770X machines apparently shipped with a BIOS setting of "00" at byte 20 instead of "02". This means that for some reason there are 600/770 machines that have a particular bit turned on by default and other 600/770 machines don't. I don't know what that particular bit controls or why some machines might have it on by default and others off.

From what I've seen, there have been no reported problems from people who have changed byte 20 to from "00" to "0A" instead of from "02" to "0A". Having said that, I personally would try to retain the original BIOS settings as much as possible if it were my machine. So I would recommend changing "00" to "08" -- this will turn on the bit that controls the L2 cache without making any other changes. If you change "00" to "0A" you are actually turning on TWO bits: one controls the L2 cache and the other serves some unknown function.

''This was exactly the situation I was in. Also, after rebooting, <tt>dmesg</tt> in Linux still reports a 330MHz Pentium II.'' [[User:Zuzu|Zuzu]] 21:44, 6 October 2007 (UTC)

I checked modifying manually the following bytes/bits from CMOS which are propably dealing with cache

2CH FD -> BD -- disable internal cache
2DH 10 -> 14 -- disable internal cache
3BH 0 -> 03 -- enable internal and external cache

None of them help. So I am starting to believe, that the problem is inside the IBM bios code setting up the caches in a PII way instead of PIII way.

I don't know if your machine has the same bios than mine 600E. Anyway, this is how I do in my 600E.

When you boot, you get bios post error 127. Then you shoud do the following:

Choose "test", choose "exit", choose "config", hit "ctrl-d", opens
bios hex-editor. Take cursor to position 20, key "02" -> "0A", hit "F2", hit "esc", choose "exit", choose "ok", and reboot.

Next boot should go without error-127

The hex-editor calculates the checksum automatically.

In case you edit the bios data and the machine doesn't boot correctly, you can always reset the CMOS data by taking out the bios cmos battery for 30 seconds. After that the next boot will preset it to initial values (you have to set the time also).

=== [http://www.wimsbios.com/phpBB2/topic4046-705.html SpeedStep and L2 cache enabled in GRUB bootloader] ===

From chantage:

hat's right. I put the code in GRUB. The speedstep mod and the level 2 cache can be enabled before booting an operating system.

Being a Linux user, I have not been satisfied with the existing solutions to enable the speedstep mod. The kernel module by wmarcusm is great but has one problem. Since it does not change the kernel's internal variables like loops_per_jiffies, time-related tasks can malfunction. If you do 'sleep(1)', it actually sleeps less than 1 second. I do a lot of timing-sensitive stuff, so it is a real problem for me.

The tsc is not recalibrated either. To make everything work properly, the kernel source has to be modified. But, if you have no problem giving up tsc, it is possible to add "clock=pit" to the kernel boot options. Then you only need to update loops_per_jiffies or cpu_data.loops_per_jiffies, which can be done in a kernel module.

But I wanted to use tsc as the time base and did not want to patch and recompile the kernel everytime I install a new kernel. So I put them in the boot loader, [http://kihwal.fayoly.net/600e/grub.html GRUB].

I am not using Windows, but if you do, it will activate the mod and enable the cache before Windows loads. It will also activate the mod/l2cache when waking up from WinXP hibernation. (If APM hibernation is used, it won't work, as APM hibernation/wakeup is implemented in BIOS and bypasses the bootloader. WinXP uses ACPI by default and implements its own hibernation method.)

Even with this version of GRUB, wmarcusm's programs will be still useful for re-enabling the feautures after waking up from suspend or APM hibernation.

One thing to note is that the port address is hardcoded. Smile Yes, it sounds stupid, but all three ThinPad 600E's that I have access to reports the same base i/o address for the south bridge. So far I had no problem on any of the three. If you do, probe it using wmarcusm's code and put that number in place of the existing hardcoded base address.

To use the feature, you just need to add "tpad" command to your boot configuration file. If you add the "--nods" option, it will only enable the l2 cache and leave the speedstep mod alone.

One final note is that, if you only have NTFS partitions, you cannot use this version of GRUB, as it lacks NTFS support. The stage2 images can be installed on linux or fat partitions. It will be great if it is ported to WINGRUB or GRUB4DOS. If you have no idea what I am talking about, just stay with your current configuration.

Enjoy!

== 9.5mm Optical drive standard and UltraBay Slim ==
The article mentions standard 12.7mm optical drive interchangeability / compatibility with the Apple iBook slot-loading drive and the UltraBay 2000. This seems somewhat obvious. However, has anyone uncovered whether the connector on the 9.5mm optical drives used in the MacBook and 15" MacBook Pro is the same (i.e. interchangeable / compatible) with the 9.5mm UltraBay Slim? [[User:Zuzu|Zuzu]] 02:48, 16 November 2007 (UTC)

I am reasonably sure a Floppy drive does not exist for the UltraBay Slim.
People are told to use a USB FDD instead.

Also the UltraBay 2000 battery is not supported in UltraBay Plus.
UltraBay Plus has its own battery that should be used

----

Anyone know if it's possible to bodge together a 770X Ultrabay II CD-RW from a Ultrabay II DVD and, say, a 600E UltraSlimBay CD-RW? Just something I've been wondering for a while.

== UltraBay II? ==

Does it seem odd that the UltraBay II was the ''first'' bay? Was there no UltraBay, or some other type of bay? -- [[User:Whizkid|Whizkid]] 00:51, 16 Apr 2005 (CEST)

----
True. ;-) It seems, that actually the drive bay in the 380 models was called UltraBay, but i don't know for sure. So i didn't add it.

== Not just IDE ==

Obviously UltraBay is not just an IDE interface.

Most also have a floppy interface (apart from the latest 'slim' and 'enhanced' versions), and can take a battery.

If I remember correctly you could get the floppy drive activated by hibernating the thinkpad and installing the floppy drive, so that on power up the BIOS would enable the floppy disk drive and it would work. This was in the old APM days, so it might work differently with ACPI.

----
You're right. I remember reading some IBM text about the UltraBay yesterday, which said that the controller is capable of dynamically changing the pin layout to support the different kind of devices (initiated by the BIOS). I'll try finding it again and correcting the information on the page.

[[User:Wyrfel|Wyrfel]] 23:16, 17 Apr 2005 (CEST)

On my 770x under ACPI, if you force the floppy driver to use 2 3.5" drives (in modprobe.conf options floppy floppy=1,4,cmos), then you get to use either external floppy / ultrabay floppy / both if you plug them in after boot time. Otherwise the autodetect only finds one. I still haven't got hotplug fully working (mostly as it depends on Linux being able to hotplug IDE devices, not just IDE controllers).

I added a page for the drive ([[UltraBay II Floppy Drive]]) containing your info. [[User:Wyrfel|Wyrfel]] 21:24, 9 Aug 2005 (CEST)

== First UltraBay ==
The oldest references I can find to the name 'UltraBay' are the ThinkPad 755 series (755CSE, 755CE, etc).

But the older 750 models already had the hot-swappable drive bay, and support some of the same options, so it looks like the 'UltraBay' started with the 750 series.

But then again, later models support CD-ROM drives (755CD, 760CD, etc), which certainly are not supported in these older models, but they are all called 'UltraBay'.

To my (limited) understanding, the SATA devices will not work in the 'older' TPs like the T4x, but the PATA devices WILL work in the latest systems, as the have both SATA and PATA support.

--[[User:Tonko|Tonko]] 20:50, 9 October 2006 (CEST)

[http://www.wimsbios.com/phpBB2/topic4046.html IBM Thinkpad 600E bios mod for processor update]

[http://www.wimsbios.com/phpBB2/topic4046-15.html ShareDoc, Aug 15, 2003:]

I got rid of the memory stability problem by disabling the 32M PC66 memeory that is built in the motherboard. I found out that byte 2B of CMOS controls the SDRAM banks. Bit b0 disables internal 32M memory. By changing the content from 80 -> 81 the 32M is disabled.

Now I have two 128 Sodimms working fine. No need more to seek for cas3.

[http://www.wimsbios.com/phpBB2/topic4046-765.html 2B is row 20 column B in the editor inside the BIOS config] - see pkiff's reply

I checked modifying manually the following bytes/bits from CMOS which are propably dealing with cache

2CH FD -> BD -- disable internal cache
2DH 10 -> 14 -- disable internal cache
3BH 0 -> 03 -- enable internal and external cache

None of them help. So I am starting to believe, that the problem is inside the IBM bios code setting up the caches in a PII way instead of PIII way.

I don't know if your machine has the same bios than mine 600E. Anyway, this is how I do in my 600E.

When you boot, you get bios post error 127. Then you shoud do the following:

Choose "test", choose "exit", choose "config", hit "ctrl-d", opens
bios hex-editor. Take cursor to position 20, key "02" -> "0A", hit "F2", hit "esc", choose "exit", choose "ok", and reboot.

Next boot should go without error-127

The hex-editor calculates the checksum automatically.

In case you edit the bios data and the machine doesn't boot correctly, you can always reset the CMOS data by taking out the bios cmos battery for 30 seconds. After that the next boot will preset it to initial values (you have to set the time also).

=== [http://www.wimsbios.com/phpBB2/topic4046-705.html SpeedStep and L2 cache enabled in GRUB bootloader] ===

From chantage:

hat's right. I put the code in GRUB. The speedstep mod and the level 2 cache can be enabled before booting an operating system.

Being a Linux user, I have not been satisfied with the existing solutions to enable the speedstep mod. The kernel module by wmarcusm is great but has one problem. Since it does not change the kernel's internal variables like loops_per_jiffies, time-related tasks can malfunction. If you do 'sleep(1)', it actually sleeps less than 1 second. I do a lot of timing-sensitive stuff, so it is a real problem for me.

The tsc is not recalibrated either. To make everything work properly, the kernel source has to be modified. But, if you have no problem giving up tsc, it is possible to add "clock=pit" to the kernel boot options. Then you only need to update loops_per_jiffies or cpu_data.loops_per_jiffies, which can be done in a kernel module.

But I wanted to use tsc as the time base and did not want to patch and recompile the kernel everytime I install a new kernel. So I put them in the boot loader, [http://kihwal.fayoly.net/600e/grub.html GRUB].

I am not using Windows, but if you do, it will activate the mod and enable the cache before Windows loads. It will also activate the mod/l2cache when waking up from WinXP hibernation. (If APM hibernation is used, it won't work, as APM hibernation/wakeup is implemented in BIOS and bypasses the bootloader. WinXP uses ACPI by default and implements its own hibernation method.)

Even with this version of GRUB, wmarcusm's programs will be still useful for re-enabling the feautures after waking up from suspend or APM hibernation.

One thing to note is that the port address is hardcoded. Smile Yes, it sounds stupid, but all three ThinPad 600E's that I have access to reports the same base i/o address for the south bridge. So far I had no problem on any of the three. If you do, probe it using wmarcusm's code and put that number in place of the existing hardcoded base address.

To use the feature, you just need to add "tpad" command to your boot configuration file. If you add the "--nods" option, it will only enable the l2 cache and leave the speedstep mod alone.

One final note is that, if you only have NTFS partitions, you cannot use this version of GRUB, as it lacks NTFS support. The stage2 images can be installed on linux or fat partitions. It will be great if it is ported to WINGRUB or GRUB4DOS. If you have no idea what I am talking about, just stay with your current configuration.

Enjoy!

I got rid of the memory stability problem by disabling the 32M PC66 memeory that is built in the motherboard. I found out that byte 2B of CMOS controls the SDRAM banks. Bit b0 disables internal 32M memory. By changing the content from 80 -> 81 the 32M is disabled.

Now I have two 128 Sodimms working fine. No need more to seek for cas3.

[http://www.wimsbios.com/phpBB2/topic4046-765.html 2B is row 20 column B in the editor inside the BIOS config] - see pkiff's reply

I checked modifying manually the following bytes/bits from CMOS which are propably dealing with cache

2CH FD -> BD -- disable internal cache
2DH 10 -> 14 -- disable internal cache
3BH 0 -> 03 -- enable internal and external cache

None of them help. So I am starting to believe, that the problem is inside the IBM bios code setting up the caches in a PII way instead of PIII way.

I don't know if your machine has the same bios than mine 600E. Anyway, this is how I do in my 600E.

When you boot, you get bios post error 127. Then you shoud do the following:

Choose "test", choose "exit", choose "config", hit "ctrl-d", opens
bios hex-editor. Take cursor to position 20, key "02" -> "0A", hit "F2", hit "esc", choose "exit", choose "ok", and reboot.

Next boot should go without error-127

The hex-editor calculates the checksum automatically.

In case you edit the bios data and the machine doesn't boot correctly, you can always reset the CMOS data by taking out the bios cmos battery for 30 seconds. After that the next boot will preset it to initial values (you have to set the time also).
