triple floppy drive question

I’ve got my “gaming” system configured with three 3.5” floppy drives as units 0, 1 and 2.  These work fine with front panel universal boot and also with HDOS (DK0:, DK1: and DK2: ).  My CP/M configuration, which boots via Quikstor, shows the following when I do a QSMAP:



E:            H-37 5” DD Floppy           0

F:            H-37 5” DD Floppy           1

G:           H-37 5” DD Floppy           0


The problem is the third drive is physically mapped to unit 0.  When I call for drive G: it prompts me to swap the disk in drive E:


I want to map G: to unit 2.  Based on a scan of the BIOS code I believe that it’s configured to allow three physical drives.  I’m just trying to figure out how to “un map” G: to E:.  I don’t see any option in QSMAP to do this. There is a QSCONFIG.COM program but it just hangs when I try and run it (wonder why?)


Can anyone help me?  No huge deal but if I’ve got three drives it’d be nice to configure the OS accordingly…

About QSCONFIG hanging .... is it just waiting (with no prompting!) for a few spacebar presses to determine the console baud rate?  IIRC, CONFIGUR also does that.

Well.  Some combination of multiple SPACE and/or RETURN characters eventually elicited a response (but it spent a long time “thinking” without telling me what it was doing…)  Thanks terry!  QSCONFIG analyzed my hardware (it found three drives) and asked me to type “Y” if it was a standard config.  I hit “Y” and now lo and behold i have three drives.  Thanks!
