Yes hd with homebrew evo 2.2 done 6 of them for family (2 in each house), no problems at all.
are you sure you got the evo-x 2.2 from a good source, maybe someone just relabeled a different bios.
I always have used maxtor 120Gb 5400 rpm drives if that make a difference (the reason being they come zero'd out)
I also used 27c040 chips, I did have a little problem with 27c4000 chips not working
and what ever you do you never want to flash the internal bios that is dumb. The only ones doing it are people who got screwed by buying a early mod that was not upgradable like they were told it would be.
