Wooh. Then the timeout here:
#define CONFIG_BOOTMENU_WAIT 2500
... is only a wait before booting the default (floppy) image and Seabios should not
be rebooting coreboot? Because if so, I'm getting an endless reboot after
failure to boot the floppy image.
Well anyways, I've pretty much gotten both my 440BX (Tyan 1832dl using Tyan
1846 mainboard and DFI P2BX using Asus P2B mainboard) working. Just raminit
seems to be spawning random bugs.
It's really nice to see these old 440BX boards being able to boot from USB pen
