Hmpf. I'll try the clock=tsc switch next. I did boot using the clock=pit
switch and the clock was normal...but I had also changed the append statement
acpi=on to acpi=off as well. I'll set it back to "on" and try "clock=tsc" in
combination.
My bios is very limited. This is a rather old laptop and there is just not a
lot I can do. I'll check it one more time as I reboot.
Thanks for the help.
