Hi Everybody, I just posted a net5501 BIOS update with: comBIOS vers 1.32h * fixed IDE DMA enable issue on net5501 * fixed soft reboot issue on net5501 * change initial clear screen to scroll lines
This all works fine now.
There might still be issues with Ultra-DMA detect/setting, I would be happy to get a few success/failure reports, just email me directly.
Under NetBSD -current, the controller reports Ultra-DMA mode 4 capability, the drive I have is Ultra-DMA mode 5 and they end up communicating at Ultra 4. Looks OK, if Ultra-DMA mode 4 (Ultra/66) is actually the top speed of the controller.
