My T30
Installing Hardware
Ultrabay SATA HDD Caddy
Using an after-market caddy causes the kernel to complain that it was "limited to UDMA/33 due to 40-wire cable". But I was able to over-ride that by adding libata.force=2:80c
to /boot/grub/grub.conf. Now connects at UDMA5, 100 MB/s.
USB 2.0 Ports
I added a PCMCIA card with 2 USB 2.0 parts on it. Automagically identified and configured. Write testing showed it 4 times faster than stock USB 1.0 ports. Command for write testing:
$ tiotest -t 1 -f 700
Read testing wasn't working right. I may just use a stopwatch.
PCMCIA CompactFlash card reader
I'm trying to get a generic PCMCIA CF-card reader to work. It's automagically seen and configured, but it's forced to PIO0 mode, which is slower than erosion. The CF card I'm using, TS8GCF133, purportedly supports DMA modes, but I can't seem to get the system to recognize that. I also can't get any PIO mode other than 0 to work. It may be the no-name adapter I'm using.
RAM
I installed a second 1 GB stick of RAM. System recognized it and seems to be happy with it. That makes a total of 2 GB.
Using It
Connecting Cell Phone
I couldn't connect my Samsung SGH-T669 as a Mass Storage device, despite having set the phone to MTP mode.
/var/log/messages:
usb 2-2: new full speed USB device using uhci_hcd and address 10 usb 2-2: New USB device found, idVendor=04e8, idProduct=f000 usb 2-2: New USB device strings: Mfr=2, Product=1, SerialNumber=3 usb 2-2: Product: Qualcomm Configuration usb 2-2: Manufacturer: Qualcomm, Incorporated usb 2-2: SerialNumber: [serialnumber] scsi8 : usb-storage 2-2:1.0 mtp-probe: checking bus 2, device 10: "/sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2" mtp-probe: bus: 2, device: 10 was not an MTP device usb_modeswitch: switching 04e8:f000 (Qualcomm, Incorporated: Qualcomm Configuration)
The problem is usb_modeswitch. It's trying to do something fancy with setting up the phone to be a modem. I disabled usb_modeswitch, and the phone connected like a USB mass storage device. (Well, the microSD card connected, which is all I wanted.)
I went to /etc/usb_modeswitch.conf and changed "DisableSwitching=0" to "DisableSwitching=1". Viola!
At some point I should see if I can figure out what the usb_modeswitch stuff should be and send it off to the developers.
ToDo
