I have a Windows 2000 server VM that boots in a stable way under VMWare Workstation 8.0. The W2K server is configured in Device Manager under Computer as MPS Multiprocessor MPC. Under VMWare it is given one core. I want to change this to run ACPI since that is much more energy efficient.
If I go into Device Manager and change the entry to any form of ACPI:
ACPI Uniprocessor
ACPI Multiprocessor
on the next boot I get a hex 7B INACCESSIBLE_BOOT_DEVICE from Windows.
It almost looks like changing the ACPI driver somehow messed with the boot.ini file. Should switching to ACPI be making any changes to boot.ini?
I read other threads here that talk about switching to the LSI Logic SCSI driver. I don't understand why that would be necessary.
