Setup Functions - Mitsubishi Electric Apricot LS Pro Using Setup And Installing Add-Ons

SETUP functions

Enable
Power-On Sound
When this option is enabled the LS Pro audio subsystem
provides an audible indication that the system has been
switched on.
BIOS shadowing
Enabling BIOS shadowing enhances the performance of
the system by copying the BIOS into RAM.
The BIOS on the system board is stored in ROM, which
has long access times, and only an 8-bit wide interface to
the rest of the system board. By copying the BIOS into
RAM the system takes advantage of the inherently faster
access times of RAM, and a 16-bit wide interface, to
enhance performance.
When BIOS shadowing is disabled, an additional 384
Kbytes of extended memory is available. Unless you have
a specific need for the extra 384 Kbytes it is recommended
that you enable BIOS shadowing.
H/D detection
When this check box is enabled the system automatically
detects the type of hard disk fitted. It must always be
enabled in systems equipped with a hard disk drive. If it is
disabled the system will not recognise its hard disk drive.
In floppy only and diskless systems this check box should
be disabled. With the hard disk detection disabled, systems
without hard disk drives will boot faster as the BIOS skips
the hard disk detection code.
