When a new configuration is launched for the first time, two error messages are displayed in the console window during the virtual hardware boot:

ERROR: ISA table corrupt!
Initializing table to defaults
type >>>init to use these changes
 
TIMER_TPS environment variable invalid
Defaulting to 1mS per tick

This behavior is similar to what happens on a real AlphaServer the first time it is powered on or when the CMOS battery is replaced.  The Time-Of-Year (TOY) and NVRAM variables have not yet been initialized by the console firmware.  Once the emulator has successfully booted to the console prompt and has then been shut down in a controlled fashion using the exit command, TOY and NVRAM information will be written to .toy and .nvr files.  The next time the emulator boots, the required information will be extracted from these files and the above errors will not occur.
