System:
Gateway GP6-350,
IDE primary master hard drive,
IDE secondary master CD-R,
128MB RAM,
external USB Maxtor OneTouch hard drive

Software: SCO OpenServer 5.0.7 Desktop with MP1/UP1 followed by
MP3/UP3.

In playing around with this test system, I noticed that mkdev hd has
options to install the USB drive but not to remove it.

How does one permanently remove a USB drive from the hardware
configuration after it's no longer wanted?

I've searched the man pages, onboard help, and online sources,
including SCO's TA area (public & member) to no avail.

Any guidance appreciated.
