Updating a sequence

You can also check the Lenovo Support website's driver matrix. Make sure the firmware bootdisk is in linux 'dd' format, as the self-extracting disks from the IBM website cannot be booted directly as such.Lenovo/IBM provides firmware upgrades in a variety of packages: The Linux diskette is just the Diskette package that runs on Linux instead of Windows/DOS. This worked on the R31, X22, T21, T30 and T41p with various firmware updates.If specified, this association replaces any previously specified association for the sequence.

If unspecified, the old cache value will be maintained.

option causes the sequence to be associated with a specific table column, such that if that column (or its whole table) is dropped, the sequence will be automatically dropped as well.

Updating the BIOS in Linux (with few exceptions) is not officially supported by Lenovo. By following any of the instructions here you are accepting the very real risk of turning your Think Pad into a big expensive paper weight, as a firmware update gone wrong can create unfix-able problems. A user on Notebook Review named 'Middleton' made these alternative BIOSes to enable SATA2 on certain Thinkpad models (X61/T61/R61/X300). Write the extracted image to a USB Flash drive using dd.

These Think Pads are limited to SATA1 in their BIOS even though the hardware is SATA2. "geteltorito" is available in Ubuntu (at least in Trusty, 14.04) from package "genisoimage".

However, a superuser can alter ownership of any sequence anyway.) enables sequence numbers to be preallocated and stored in memory for faster access.

The minimum value is 1 (only one value can be generated at a time, i.e., no cache).Note: If your BIOS-Update tool says that no update is needed, then simply downgrade the Bios first: On Lenovo's drivers download page, the old Bios files are listed at the very bottom of the page. If you really want to do it with a floppy, some tips: BIOS, ECP, CD/DVD and Harddisk firmware disks can be booted over the network with PXELINX as part of the SYSLINUX package.A list of links to firmware downloads can be found at BIOS Upgrade Downloads for most Thinkpad models. This requires that you have a DHCP and tftp server configured and setup properly on your network, and is probably not for the faint of heart.You must read the Lenovo website and/or files to confirm which BIOS is compatible with which ECP, and the order in which to update them. (This will destroy the data on it, of course.) Acquire a pure DOS boot cd such as Windows 98 recovery CD and boot that.The Lenovo/IBM documentation is sometimes unclear about the order in which these two firmwares should be updated. IBM didn't provide specific instructions for your model or a particular firmware update), update the ECP first, and then the BIOS. Use F8 to abort the boot sequence of a windows 98 boot CD.Also, make sure to do the two updates immediately one after the other. If you need CD-ROM support, load CD-related things but say no to everything else.
