Yes. It's interesting that comparing the differences in north bridge registers between windows unpatched, and the latest 1.05 raid patch is just register 0xb7 changing. Perhaps I'll be 'brave/foolish' and just twiddle it with setpci after backing up. Do you have documentation for these registers ? I've been kicking through via's site looking for chipset datasheets to no avail. I toasted one of my raid disks trying to get Win98se installed over the weekend to do similar testing here. Didn't like the size of the disk I tried to install it to, and I ended up with a zapped partition table and who knows what else. Thankfully the software raid 5 coped perfectly (thanks guys!) and the system was back after the rebuild time. I've a spare (small) disk to try this with my system today or tomorrow. Which ABit bios are you using on that test system currently ? I put the newest ABios bios (7P vs 65) on my system (KT7A-RAID v1.3) and it appears to have gained me about 3-4MB/sec over the PCI bus. (54MB/sec vs 50MB/sec) Attached files are my raw pci data for 00:0 and 00:1, for your reference. It's different enough to your data that it's not easy to compare though.
