From Earlham Cluster Department
All nodes in LittleFe must be running PhoenixBIOS >1.16 in order to do Linux PXE booting properly. One smoked node that got returned came with 1.13, and upgrading turned out to be a major PITFA. Here's the procedure I eventually settled on:
- Burn a Win98 CD.
- Boot off a USB CD drive to DOS mode.
- Have a USB floppy hooked up, with the flash utility (awfl823b.exe) and the new BIOS image ready.
- After booting, cd to b:, and run awfl823b and input the name of the new image. You should choose to backup the old BIOS.
