[comp.os.minix] 2nd floppy access hangs MINIX

misha@nsc.nsc.com (Michael Umansky) (06/25/87)

This is a supplement to my previous posting about having problems with
floppy drives.  After more checking I found that if I stay with floppy
drive A (0) and do not access floppy drive B (1) the system runs fine.
As soon as I either mount a floppy on drive B (1) or do some IO operation
to that drive the system hangs and F1 shows the process waiting for FS.
Also, initially 'update' in F1 will show waiting for MM (idle) but then
when it kicks in it also hangs waiting for FS and only reboot saves.
On a separate note, I compiled and ran the 'readfs' utility posted by

on my Venix and it ran perfectly.  You have to get the necessary include
files from MINIX floppies to your target system except for 'stdio.h' which
should be your local one.  I also removed unnecessary passing of a file
descriptor for special device and made it global.  There was one long name
conflict starting with 'special' which is easy to fix.  Thanks to Paul
for a useful utility.
