SYMPTOMS
========
You may receive the following error message if you attempt to install MS-DOS
from a drive other than A:
Current Drive Must be set to A
CAUSE
=====
This error message can occur when one or more of the following conditions
exists:
- Your CMOS settings are incorrectly set and do not include your floppy disk
drive.
- You are using a high-capacity optical drive with removable disks (called a
"floptical" drive) and the device driver for it is incompatible with Setup.
- You are using an external floppy disk drive and the device driver for it is
incompatible with Setup.
- You are using a 2.88-megabyte (MB) floppy disk controller. (Some of these use
extended BIOS chip sets that are incompatible with Setup.)
WORKAROUND
==========
If your drive C has at least 9 MB free space, you can work around this problem
by copying the MS-DOS 6 Upgrade files to your hard disk drive and running Setup
from your hard disk drive. To do this, use the following steps:
1. Create a temporary directory on your drive C. For example, type "MD DOSTEMP"
(without the quotation marks) at the MS-DOS command prompt and then press
ENTER.
2. Copy the MS-DOS Upgrade files from each floppy disk to the DOSTEMP directory.
For example, type "copy b:\*.* c:\dostemp" (without the quotation marks) at
the MS-DOS command prompt and then press ENTER.
3. To run Setup, type "c:\dostemp\setup" (without the quotation marks) at the
MS-DOS command prompt and then press ENTER.
