I was wondering if someone out there cound help me. Just recently
I setup a model 30 and attached the 5 1/4" IBM adapter drive to it
and found out that I could no longer use the normal B drive. Since
the ribbon cable for the B drive is now connected to the adapter
board for the 5 1/4". Is it possible to create a cable with a switch
in it so that I could use the normal B drive or the 5 1/4" drive with
out opening up the case? The reason I want to do this, is because
the 5 1/4" drive will be attached permamently, and I still want the
option of having 2 3 1/2" drive for functions like COPY A:*.* B: nd
DISKCOPY A: B: and the like. Could anyone out there tell me if this
is at all possible?

It is possible, but impracticle. The reason being is that the new PS/2
line now loads into its parameter tables the kind of drives that are attached
when the system boots. If you boot with a 5.25" floppy and then change it
to a 3.5" floppy, then the system will still think that it is 5.25".
Just do a DISKCOPY A: A: for the 3.5" to 3.5" copies. This still doesn't
fix a copy or xcopy problem. In this case, the cure is to use PC-DOS 3.21,
or over, and assign a logical drive to A:. Do it by adding the following
to your CONFIG.SYS file:
DEVICE=[d:][path]DRIVER.SYS /D:0
If you have a hard drive attached to your system and the DEVICE comes before
any VDISK entry, then the logical drive will become D:. If there isn't
a hard drive, then the logical drive will become C:.
This will allow you to copy files from A: to C: (or D:) without any trouble,
except of course for the fact that you will have to swap diskettes).
