Did the intel updates yesterday, uninstalled, and installed the IDE channel again. When XP reinstalls, it is set to DMA 2 on the master (NEC), and DMA 4 for the slave drive, which is a BTC 1008. The NEC still freezes when I try to use it on DMA 2, and won't work until XP forces it back to PIO. The BTC works on DMA 4 fine.
So I tried switching the NEC to slave and BTC to master, same results. The BTC is DMA 4, but the NEC freezes until forced back to PIO.
My HDD setup is, one Raptor 36GB SATA onboard, and one 160GB hitachi on a Ultra IDE PCI controller. I've tried burning from the Raptor and the Hitachi, sames results, 1.8X on the NEC.
Edit: I've also tried the NEC by itself on the IDE channel, so having two drives isn't the issue. I got the same thing, won't work until forced back into PIO mode. Odd thing, is that the BTC works fine on the same cable, no issues. Weird.
