With access mode set to "lba" (this is the same for "large"): Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller at PCI slot 0000:00:11.1 ACPI: PCI interrupt 0000:00:11.1[A] -> GSI 11 (level, low) -> IRQ 11 VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci0000:00:11.1 ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:pio Probing IDE interface ide0... hda: MAXTOR 4K040H2, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 Probing IDE interface ide1... hdc: ASUS CD-S500/A, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 128KiB hda: 78198750 sectors (40037 MB) w/2000KiB Cache, CHS=65535/16/63, UDMA(100) hda: cache flushes supported hda: hda1 hda2 hda3 hdc: ATAPI 50X CD-ROM drive, 128kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.20 I will try the 2.4 kernel on wednesday.
