Thanks for your suggestions! They are really helpful I still have some more detail questions, --------- 1 Is linuxbios a "real" linux? I mean can a normal linux app run on it? We want the user to use this app to recovery a faild pc, so we need the app in BIOS, not harddisk 2 I am still not sure about the linuxbios/awardbios coexistence stuff. Al mentioned DualBIOS, but as long as I know, that means mainborad holds 2 biso chips, and if one fails, mainboard will use the other. (Correct me if I am wrong, I don't know much about this) But I need the award bios be used in normal case, and if the user hit some key while booting, the computer will switch to linuxbios, which will load the backup/recovery appliaction. I think the IBM app works this way.
Thanks for you help!
