SeaBIOS (version pre-0.6.2-20110924_103542-vasn250) Press F12 for boot menu. Booting from Floppy... Boot failed: could not read the boot disk Booting from Hard Disk... Boot failed: could not read the boot disk No bootable device. I can't see any activity on my floppy or hard disk and I've tried to hit F12 but nothing happens. To be able to do further testing I have ordered a new BIOS and I will also try to find a "RD1-PMC4 Bios Savior". This will enable me to have dual BIOS on my board and easily switch between them with an external switch. /Kent -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
