Vyzera to tak ze budete musiet experimentovat s jadrom. Odporcuam stiahnut
2.2.19 s IDE patchom a v nom zapnut podpru PIIx

-> kernel 2.2.16
-> chipset Intel 430VX Triton III

-> /dev/hdc:

-> Model=Maxtor 2B020H1, FwRev=WAH21PB0, SerialNo=B1CZXTME
-> Config={ Fixed }
-> RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57
-> BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=off
-> CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=40020624
-> IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
-> PIO modes: pio0 pio1 pio2 pio3 pio4
-> DMA modes: mdma0 mdma1 *mdma2 udma0 udma1 udma2 udma3 udma4 udma5
