| [[http://forum.giga-byte.co.uk/index.php?topic=8585.0;wap2|User 'kondra' on the Gigabyte forums did a good write-up on this]], reproduced below. Suffice it to say that the firmware (stupidly) looks at the C/H/S ending entry of the first partition to help figure out disk geometry (well, it actually ignores this info, as does the OS, but boy does it choke if it's not a preferred value). Fix by changing the bytes at disk offset 0x1C3 to "FE FF FF". | ===== Quick fix ===== |
