linuxbios.rom is a rom image for booting the WT300 off a IDE/CF-card. It uses the serial port (115200,n,8,1) as the console. The kernel image should be in the root of the EXT2-formatted first partition of the HD, in a file called 'vmlinuz'. If you want to put something else as the payload of the linuxbios image, you'll have to download the .tgz in this directory and compile linuxbios yourself. Mind you: The Linuxbios-image doesn't support for the SoundBlaster-emulation of the Geode, and I haven't got the VGA-output working yet. I haven't tried to access the DiskOnChip, so I'm unsure if it works or not. As an alternative, the WT300.bin-file contains a development BIOS for the WT300. It's a complete Award PC-like BIOS. It does have 2 snafu's though: It needs a battery installed in the BT1-location and it doesn't seem to boot with the original DiskOnChip in its socket. For all the roms: I haven't found a way to let the WT300 flash itself yet, so you'll have to manually flash the images in the BIOS-chip using appropriate programming hardware ('eprom-programmer')
