Hello Grant
You are correct. I have found the same thing. I had 4 fast PC's crash
last ARRL (see arrl m/m kl7ra (long)) on the contest reflector. I was
able to crash the machines using Ctl J and a quick scan every time.
I finally found an old config.sys file from an old non-crashing machine
that "fixed" the problem on all four PC's. I went for the smartdrv setup
as the cause and assumed the normal MS DOS defaults were not
correct. I will check the stack size, but thought I had disregarded that
as the cause early in the troubleshooting.
I have been hesitant in posting the above as I had several "false"
fixes.
Also the manual now clearly states to use smartdrive and gives the full
command line.
The reason this doesn't come up much is most people don't reformat
the hard drive and remove windows. The older, slower machines
seem to be fine.
If you take a P90 and reformat the drive and install 6.22 with a simple
config.sys file it will crash with CTL J menu as you scan down the page
somewhere around the M's. At least 4 machines do here.
If you load a pretty complete config.sys file with emm386, dos high,
smartdrv with big buffers and now maybe a large stack the lock-ups
stop.
So far!!
