Hi, I'm trying to fix a copy of VirtualRPC-SE running on my mums Laptop (HP nx6110). It's been running fine for quite some time, then it wouldn't boot comming up with an error something along the lines of !Boot not found missing file (or something similar). I discovered that an ADFS disc partition had been created, so I clicked on the file to set it back to boot from HostFS. Since doing this it takes ages to boot up - running very slow, but it seems to be as if it's the disc access speed that is having a problem, as when an application is up and running I can drag around the window and desktop redraw is as fast as usual and most action seem responsive as usual, so long as nothing acesses the harddrive.

I'm wondering if it's down to some settings being wrong (which I seem to recall fixed a similar speed issue in the past). I've re-applied/OKed the VirtualAcorn setting is from Tool->Options, and also gone through some CMOS config settings in RISC OS, but nothing yet has fixed it. This is the current *Status output - can anyone spot anything that look wrong?

Also, I notice in even if I delete the file, after running VA, a new HardDisc4.hdf file is being created in Models\Arm7 RISC OS 4 (JIT)
Is this correct, or is there something set that is still trying to use an ADFS disc image?

Any help much appreciated as I've got to try an fix this before my folks come back off their holidays and want their computer back.

The initial error about "File &.!Boot not found" would indicate that the RISC OS CMOS file had got corrupted or blanked.

The solution is to run the CMOS Restore application which can be found in the Utilities section of the VirtualAcorn installation CD. Quit VRPC. Insert the VirtualAcorn CD. Wait for the menu to load, then click on the utilities section and then run the app to restore the CMOS.

If you delete the ADFS harddisc4 file then VirtualRPC will re-create a file of the correct size on a re-start. This is correct behaviour. Unless you have a backup then anything on the original ADFS hard disc image will now have been lost.

Reverse the changes you have been making and then run CMOS Restore.

I'm very grateful for this tip. Photoshop Elements froze while SA-VRPC was minimized and Ctrl/Alt/Del couldn't clear it. In switching off it destroyed the VRPC Boot setup. Using the CMOS utility cured the problem though some setting need to be restored. Thanks.
