[LinuxBIOS] flash_rom output from a sis chipset

[Jeff Carr]

I tried the linux bios flash_rom utility today on a sis based board. I
tried to read out the bios as a file. It failed. (output below)

flash_rom says: "Trying MD-2802 (M-Systems DiskOnChip Millennium
Module), 8 KB". Interestingly, the second google hit of "M-Systems
DiskOnChip Millennium 2802" was the linuxbios wiki :)

I thought I'd post the output for informative purposes. I'd dig more if
anyone was interested.

Is the BIOS chip on this machine really only 8KB in size? I find that
really hard to believe.
