yo you don't need the /s with the /b if you're in the i386 dir. Just use from x:\i386>winnt /b. below is the script your looking for. Oh and the /b means don't make floppies just install. As for your deal with the nic. If when you load the driver's it hoses NT with a BSOD and won't boot, just make a copy of the hardware config in system properties, i.e. right click my computer > properties. specify the menu to show for 1 sec, that way if you install driver that hoses it you just load the copy of the hardware config and it won't load the driver. the debug script below will take any partition of the drive. Just boot from a win98/me floppy and type the command under the comments section. the debug exchange section is what you will see returned.

reboot the machine and partition the drive. i've used this a few times on 2 different maxtor 20gb drives. i got the script from a friend at school, it came from toshiba and was written by them in 1994 so use this at your own risk!
