Version 3.00 is the initial release of the Ascentia 950N 90 MHz System 
BIOS/Japan version.

This initial release contains software included with the system either on the 
hard drive or in diskette form, at the time the system originally shipped 
(First Customer Ship date or FCS).

This release does not contain any known fixes or enhancements.

If for some reason the original software becomes corrupted, 
and the user can not retrieve the necessary files from the system's backup
directory, the user may use the initial release to restore the software to 
factory default conditions.
