Hello everyone. First of all, thank all of you that have worked on this driver. Now, the problem. I installed a TX4 into my Dell PowerEdge 1300 and am having IRQ timeout problems. I'm not sure if it is a RAID driver issue or an ATA driver issue, but I thought I'd start here. When booting, I get the following: PDC20268: IDE controller on PCI bus 03 dev 08 PDC20268: chipset revision 2 PDC20268: not 100% native mode: will probe irqs later PDC20268: ROM enabled at 0xf8000000 PDC20268: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary MASTER Mode. ide2: BM-DMA at 0xccc0-0xccc7, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0xccc8-0xcccf, BIOS settings: hdg:pio, hdh:pio PDC20268: IDE controller on PCI bus 03 dev 10 PDC20268: chipset revision 2 PDC20268: not 100% native mode: will probe irqs later PDC20268: ROM enabled at 0x000dc000 PDC20268: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.

I cannot do anything with the array after booting. I suspect it's an IRQ problem, but am not sure.

I have looked on google, but nothing pops up. Can anyone help? Jeremy -- Jeremy Worrells jworrells@xxxxxxxxxxxxx 801.270.8616
