May it be because of ServerWorks chipset (support for ServerWorks was compiled in)? or SMP? Here is except from dmesg: Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ServerWorks OSB4: IDE controller on PCI bus 00 dev 79 ServerWorks OSB4: chipset revision 0 ServerWorks OSB4: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:pio, hdd:pio hda: FUJITSU MPG3307AT, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hda: 60046560 sectors (30744 MB) w/2048KiB Cache, CHS=3737/255/63, UDMA(33) I will appreciate your help, -igor p.s.
