BIOS Upgrade
When upgrading from a Windows installation, a BIOS upgrade is quite simple if you follow the IBM instructions, as described on the IBM page. (Link will follow soon...)
For other operating systems there is an option to create a bootable floppy disk. This is described on the IBM site as well. (Link will follow as well soon...)
The whole thing gets more complicated if you neither have Windows neither a floppy drive installed. This is what this page is intended to describe.
