The see whether either your Win 95/98 or FreeBSD installs are more promising. I have seen instances where either a drive or particular MB chipset/BIOS rev seemed incapable of working at the stated modes. My guess is that NT's IDE drivers are exceedingly conservative, and probably already run the drive at PIO mode 0, while Windows 95/98 use the BIOS info and try to drive the chipset/drive at the probed rate (and fail!). Recent revs of FreeBSD may also be able to use high rates based on probed info, in which case you may need to do some mailing list searches to identify any way to disable the feature (if it in fact exists). -- Andrew I MacIntyre "These thoughts are mine alone..."
