I think you can turn autoconfigure off in SYCONFIG or something
like that (or by setting autoconfig SYSGEN param or somesuch?)

Since you're in IOGEN, you're better off building a small umbrella
routine that calls IOGEN$AUTOCONFIGURE, and then you're stuck with
DELTA or XDELTA, so far as I know.  (I did this stuff using DELTA --
a royal pain in the neck, since you need about 33 maps and 2075 listings, all 
handy essentially simultaneously....)

The reason is that AUTOCONFIGURE spends most of its time in EXEC
mode at IPL 0, and you can't use the system code debugger in EXEC
mode (or at IPL 0 -- at least you couldn't on V6.2, where I was
screwing around with this stuff).

So, turn autoconfigure off, then DEFINE LIB$DEBUG DELTA, and run the test
jig that calls IOGEN$AUTOCONFIGURE, using Delta.  It'll certainly keep you off the 
streets......

I don't know if I still have my little test jig around anywhere, but
I'll check and let you know.

I'm trying to debug mods to iogen-scsi-config, wondered if you
have some pointers.

The image starts off after VMS is running enough to have some
system services, and can be delayed by booting with startup_p1
set to "MIN". However when I link it /debug I get the process
deleted. (I want to debug the user mode stuff, which is where I
suspect the hangs are.) The system debugger gets in trouble here
(works ok for the kernel stuff) so I thought it would be best to
try a normal debugger. However I hate this blind alley business.

Got any pointers?
