Zenith Multiboot Option and MS-DOS 5.0 (75192)
The information in this article applies to:

• Microsoft MS-DOS operating system 5.0a

The setup/diagnostic shell built into ROM on Zenith computers normally
allows you to select several different drives as the boot drive. Under
MS-DOS 5.0, the only options that will work are the first hard disk
(C) and the first floppy drive (A).
The setup/diagnostic shell is invoked on some Zenith computers by
pressing the CTRL+ALT+INSERT key combination. This shell will accept a
number of commands, one of them being the command that switches the
boot drive. The normal syntax of this command is as follows:
F = Floppy
W = Winchester (hard drive)
0 = the first drive
1 = the second drive, and so on
For example, BW0 means boot from the first hard disk (C), and BF1
means boot from the second floppy (B). By design, MS-DOS 5.0 can only
boot from the first hard drive (C) and the first floppy drive (A).
Consequently, the only valid options under MS-DOS 5 are BW0 and BF0.
