If the disk contoller is not auto detected, SBS will blue screen with a STOP: 0x0000007b Inaccessible Boot device during the first reboot. To continue the install, boot from the 3 setup diskettes and press F6 when you see Windows NT is now detecting your hardware. When asked to specify devices to install and you are prompted for the OEM drivers, choose skip. At the next reboot you will receive another STOP: 0x0000007b Inaccessible Boot device. As the conversion to NTFS has not yet occured, boot to a MS-DOS floopy and copy the OEM driver to winnt.sbs\system32\drivers.

When you restart, setup will continue normally.
