- Before you start replacing SIMMs you may wish to wait for the outcome of my
- TRAP and IPE adventures (see thread "OS/2 has fallen and it can't get up").
- The
- latest story from IBM is that my 1989 AMI BIOS can't cut it. Well since I was
- considering an upgrade anyway I proceeded to order Mr. BIOS. I expect to have
-
- this installed and tested by Thursday and will post my results on Friday.
- Stay
- tuned.
