PSD=ACPI.PSD /SMP /APIC

and rebooted.

Boot failed almost immediately stopping at the ""Loading USBEHCD.SYS"" and then displaying a TRAP 000d.


I edited CONFIG.SYS and removed all USB drivers. 

Reboot failed when loading uniaud32.sys so I edited CONFIG.SYS and removed uniaud drivers.

System could then boot to a working Desktop; Log files created and attached.


Use of tmrtest.exe reveals the necessity for the /TMR switch; as I also want audio and USB support I changed the CONFIG.SYS line to

PSD=ACPI.PSD /SMP /CD /TMR /APIC /!NOD

and rebooted - successfully.

Polling is enabled.

System seems fairly stable in use but I discovered there is a problem with USB attached drives:

I can attach a usb drive and copy a few files from or to that drive without a problem. However longer use than around 6 minutes results in the system locking up requiring a press of the Reset button - regardless of whether I'm using WPS or VIO window for file copying.
