I am using SCO 3.2v4.2 and the machine will not boot. I don't
understand why. It had been booting fine, then all of sudden it stops
right before the file system is loaded and stays on H_5 with a flat
cursor in the middle of the H and 5 blinking. I have looked trough
this whole newsgroup and visited the technical articles online and have
found nothing at this point. So I hope someone out there knows
something about this.

Things I have tried -
replace the hard drive
use my boot/root floppies
tune the kernel at the boot prompt (changing the ct and disabling sumo)

None of these worked. Every time it comes up it still stalls on H_5.
Thank you for help in advance.

At H5 the kernel is initializing the file table or the root hard disk file
system (depend on whether it is* during H5 or when entering H6. My
best guess is that the file system is corrupted somehow. When you
re-installed did you copy only the data or did you over-write the new hard
drive with your old OS?

Another thing that can cause a system to hang at this point is if you are
using a SCSI controller that does >1GB translation and you have changed the
translation mode on the controller from on to off (or off to on), but have
not low-level formatted the hard drive after making the change.
