Hey all, I have a motherboard (ECS K7VTA3 V3.1) with onboard RAID from promise using the chip PDC20265R. I bought two Maxtor DiamondMax 80Gb identical drives. I am booting off of a already functional gentoo linux system using a 46Gb disk on ide0. hda is the 46Gb, hdb is a 1.6Gb, hdc is a cdrom, hdd is a cdrw, hde is 80Gb#1, hdg is 80Gb#2. When booting with the drives hooked up and the disks in a RAID0 container the kernel only gets this far and then hangs forever: Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller on PCI bus 00 dev 89 PCI: No IRQ known for interrupt pin A of device 00:11.1. Please try using pci=biosirq. VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later VP_IDE: VIA vt8233a (rev 00) IDE UDMA133 controller on pci00:11.1 ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:DMA ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:DMA PDC20265: IDE controller on PCI bus 00 dev 78 PDC20265: chipset revision 2 PDC20265: not 100% native mode: will probe irqs later PDC20265: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode. ide2: BM-DMA at 0xd400-0xd407, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0xd408-0xd40f, BIOS settings: hdg:pio, hdh:pio The next part should be the actual drive assignments, but it never gets that far. I downloaded the archives for this list and sifted through them, but didnt see anyone with my chipset that actuall hung at this part. I also followed the directions from www.murty.net/ataraid/ and got the same results.
