<p>209.183.120.137: bios/controller update sequence</p> <hr /> <div>I have disabled the hidden partition to make more space for linux (24G). I still have Windows on the 14G partition. Is it safe to upgrade the BIOS without the hidden partition? I want to get a newer BIOS to fix the annoying fan issue. Thanks<br /> <br /> - yes don't worry about it. bios upgrades have nothing to do with whats inside the harddrive.<br /> <br /> == BIOS upgrade over PXE ==<br /> <br /> Hi,<br /> <br /> I have a Thinkpad X20 with a very early BIOS and Embedded Controller Program which I'd like to update. Currently, the only feasible way of doing this is over the network using PXE. I already have a fully functional PXE server using SYSLINUX, and have so far been able to boot the BIOS diskette image using MEMDISK, although I have not attempted to flash anything yet due to the warnings given on the page. Is there any safe way I can update both the Controller Program and the BIOS in the same session over the network in this manner? If not, what other methods would be suitable? I have a USB CD-ROM drive and could probably get hold of a USB floppy drive.<br /> <br /> Thanks.<br /> <br /> Update: I ended up burning CDs as described and successfully updated everything. I'd still like to know if there is a way I could do it entirely over the network, though.<br /> <br /> <br /> == RE: grub initrd ==<br /> <br /> &quot;Another possibility which works even without a CD-drive or network is to boot the disk image via the grub initrd mechanism.&quot;<br /> <br /> 0) Interesting suggestion. Might be better of in its own section.<br /> <br /> 1) Could you please elaborate?<br /> <br /> 2) My first guess (pending your elaboration) would be to &quot;chainload&quot; the first block of the diskimage using the grub commandline, like:<br /> blocklist (''path'')/''to''/''diskimage''<br /> chainloader ''blockvalue''+1<br /> <br /> But that's just a guess!<br /> <br /> [[user:Pebolle|Paul Bolle]] Fri Jul 15 12:20:47 CEST 2005<br /> <br /> == bios/controller update sequence ==<br /> <br /> The article says:<br /> &quot;If you go through the readme's on the IBM site they'll cleary state that you must update the Control Program first, then imediately update the BIOS&quot;<br /> <br /> When I look at the IBM udpate instructions for the T23, it says:<br /> &quot;If you need to update the BIOS as well as the Embedded Controller Program, update the BIOS first.&quot;<br /> <br /> <br /> Comments?</div>
