Updating bios xp

More often than not, this tool will clearly show the You'll first need to locate the online support for your computer or motherboard maker and then download and run the tool.

No need to actually update anything, so skip those later steps in whatever instructions are provided.

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. 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.

A list of links to firmware downloads can be found at BIOS Upgrade Downloads for most Thinkpad models. 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.

It is important to understand that Thinkpads from IBM have two separate firmwares: the BIOS, and the Embedded Controller Program (ECP). You can find them at the page BIOS_Upgrade/X_Series. In that case, extract the disk image with cabextract as per instructions above and dd it to an usb stick.

A given BIOS version will require a certain version of the ECP. (This will destroy the data on it, of course.) Acquire a pure DOS boot cd such as Windows 98 recovery CD and boot that.

Updating BIOS isn't something you do manually, not completely anyway.

In most cases, you'll use a special BIOS update tool supplied by your computer or motherboard manufacturer to do the job.

As part of some hardware troubleshooting processes, especially those that involve new RAM or a new CPU that won't work correctly, updating BIOS to the latest version is a good thing to try.Note: This method works when your computer isn't starting properly if the BIOS update tool for your motherboard is bootable.In other words, if the BIOS update program supplied only works from within Windows, you'll have to stick to Method 1.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. Use F8 to abort the boot sequence of a windows 98 boot CD.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. If you need CD-ROM support, load CD-related things but say no to everything else.
