I'm reposting this enquiry because I'm still haven't resolved
the issue. I am able to boot with hdimage.first, with a floppy,
but not bootdir.first. I followed the instructions in QuickStart
to set up bootdir.first. The system files are identical to those
in hdimage.first and on the floppy. Why am I getting these error
messages? Nobody replied to my original enquiry (below). Is this
because my mistake is embarassingly obvious (like, RFTM), or because
everyone is mystified?
Thanks for your help,
Roger Young.

I set up a bootdir.first (generated by ./setup-bootdir) with MSDOS 6.22.
Booting to this results in "Invalid system disk" error.
The dosemu error log gives repeated instances of
SIGILL while in vm86()
ERROR: LOCK prefix not permitted
Are these error messages connected? Any suggestions as to what
might be going wrong and how to fix?
Thanks for any help,
Roger Young.
PS I haven't had this problem with earlier versions of dosemu...
