But if you use some other BlOSes with the switch settings
(SW1-1, SW1-2, SW1-3) for total 32-bit memory larger than
the physical DRAM installed, there will be an error message.
This is caused by different methods of testing memory among
BIOSes. The solution is to set the switches for the total 32-bit
memory in accordance with the physical DRAM installed. Most
of the BlOSes do not have this problem.
• If you want to add a 16-bit extension memory card to the
mainboard, total 32-hit memory must match the switch set-
ting for total onboard 32-bit memory plus that on the PEI-307
32-bit extension memory card.
For example, if the switch setting for total 32-hit memory is
6MB, you'll have to fill out the complete 6MB (5MB onboard
and 1 MB on the PEI-307 card) on the system before you can
add a 16-bit extension memory card. Otherwise, there will be
a memory address conflict.
