Alan,
Thanks for the quick reply. I got into my bios setup and couldn't find any switch which had the words 'concurrency' or 'streaming' in it. I believe my chipset's bios or CMOS setup or whatever is one level down from one which can tweak these parameters. I don't think I have the capability to turn off concurrency or streaming. A listing of what options I do have when in my bios is linked below. In my subsequet investigating I got lost in the strange world of flash bios upgrades and after much staring at the screen believe any upgrades would not give me the menu options I need, just fix the bugs in the current bios and keep the same menu options. (sorry if I am misusing words, am not a hardware guy). I did find a page somewhere which described a setup which did have concurrency and streaming options to turn on and off, but it wasn't for my chipset.
I did dig up a post by Frank de Lange who said he had a 'fix' for the exact same problem I am having. His solution can be found here:
http://boudicca.tux.org/hypermail/linux-kernel/2000week02/0367.html
I tried what he did, adding the line with the + in /usr/src/linux/drivers/pci/quirks.c, but changing the second argument to PCI_DEVICE_ID_INTEL_82430 since that describes my board:
From his post (a link to the full patch is above):
> { PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_82C586_0, quirk_isa_dma_hangs, 0x00 }, > { PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_82C596_0, quirk_isa_dma_hangs, 0x00 }, > + { PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_82437, quirk_isa_dma_hangs, 0x00 }, > };
I rebuilt the kernel, and it still locked up faithfully as before under the same conditions.
Can anyone help? I seem to be very close to finding a solution but not quite there yet.
For a list of what options I have in my BIOS, see

It's a google cache, but at least it's HTML. A PDF file of the same can be found at
