VirtualAcorn Recovery Utilities

This page contains links to downloadable recovery utilities designed to help get a copy of a VirtualAcorn product running again after a problem.

The downloads on this page are in Windows format and need to be opened and installed via Windows. If VirtualRPC is running these recovery utilities will not work so make sure you have closed VirtualRPC down before continuing.

Make sure that you are using the correct utility for your copy of VirtualRPC by checking the CD serial number before you start.

CMOS Repair Utilities

On a 'real' RISC OS computer RISC OS uses 256 bytes of battery backed memory to store various configuration options, for example which filing system to use and which drive to boot from. If the backup battery in a 'real' RISC OS machine goes flat all of the information gets blanked and the machine won't boot into the desktop. On a VirtualRPC a similar thing can happen if the CMOS.ram file is open and the power to the PC is suddenly removed. For example if there is a power cut or a laptop battery goes flat whilst the laptop is running.

These utilities will replace the damaged CMOS.ram file with a new working replacement without you having to perform a full re-install of VirtualRPC.
