| + | The "[[http://www.ioss.com.tw/web/English/RD1BIOSSavior.html|RD1 BIOS Savior]]" from [[http://www.ioss.com.tw/|IOSS]] is a US$30 device that can plug into a motherboard BIOS ROM socket to allow manual switching between two BIOS chips. This allows you to boot from one BIOS ROM and then switch to a second BIOS ROM chip for trial flashing. If the new BIOS fails, you can switch back to the first, unmodified BIOS ROM, and try again (info from [[http://en.wikipedia.org/wiki/LinuxBIOS#Developing_and_debugging_coreboot|Coreboot]]). | ||
| I am currently using a large number of J7F2WE based motherboards for a computing cluster. The machines have no local storage at all, just a 1 GHz Via C7 processor and 1 GB of RAM. The on-board NIC on the motherboard is based on the VIa Rhine II chipset. My machines also have three more NICs per box, but they don't factor in to getting gPXE loaded. gPXE replaces the Intel PXE code included for the on-board NIC. | I am currently using a large number of J7F2WE based motherboards for a computing cluster.
