 +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 plugs into the motherboard BIOS ROM socket and allows manual switching between two BIOS chips. ​ This allows you to boot from one BIOS ROM, 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|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. ​ 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.
