Thank you, Aussie
, for the patience
I guess you are talking about the line saying "add Intel ICH5 Serial ATA" under "Summary of changes from v2.4.21-rc2 to v2.4.21-rc3"; I don't see anything sata or ata related in the 2.4.21 change log file (nor 2.4.20, 2.4.19, and also upper). I searched with the "search" button, of course.
Also thank you xodustrance
for the suggestion; we will see if we're able to install mdk9.2 whitout tricks (he still couldn't get some pieces of the computer
, so we still couldn't install anything). If it doesn't work, I'll ask a bit more on your suggestion (I don't know what to do once you have compiled the kernel, unless you mean we install LFS or something like that)
