Hi! Ok, that means Andre's patch works. Congrats, Andre! Now, could you send me 'hdparm -i /dev/hdb' for the ZIP? It seems to be in SWDMA0 mode, which is interesting, because I thought it can't do that. You probably have some newer model. Do all your drives work correctly now? Thanks for your e

I am currently booted into a 2.4.0-test10-pre1 kernel with two modifications, the VIA 3.6 drivers you have provided and the Patch from Andre that you sent. My IBM is the primary master with the zip as its slave and the Kenwood is the secondary master with the Plextor as its slave. Here is my /pr

I have tried moving the Kenwood CDROM and the Zip between channels and this works well. I would get rid of the zip if it was a viable option but need it to do transfers, and the IBM has a real UDMA 66 cable and upto ATA 100 capability so I wanted to take advantage of it. Thanks to all that helpe
