Just put together a (mostly) new system, but I salvaged the DVD-Drive (the problem drive), a Sony CD-RW, and a ZIP 100 ATAPI off of the old system. Everything is hooked up to a Shuttle AK38N with an Athlon XP1700+. Doesn't matter which channel I use for the DVD drive or whether it's the slave or master on a channel, it won't come out of PIO mode. If I put it on the same channel as the CD-RW, it puts them both into PIO mode so I am stuck putting my CD-RW on the same channel as my HDD amd keeping the DVD on the channel with the ZIP drive. The drive is recognized by the BIOS and during the boot-up as being in DMA mode, but Windows XP just doesn't see it that way. The only way I can make it run in DMA is if I uninstall the IDE channel from the Control Panel , shut down the system, hook up the DVD and restart the system. When Windows reinstalls the drivers for the IDE channel and I set it 'DMA if available' it puts the DVD into Ultra DMA Mode 2 (along with the CD-RW on the same channel), but it switches back to PIO mode as soon as I reboot. There are no drivers or firmware upgrades that I could find. Replace the drive? Any ideas?
