SUMMARY
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).



MORE INFORMATION
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:

B [{F|W}][{0|1|2|3}][: ]

where

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.
