[DRAM and ECC]
If all your DRAM modules have parity chips (e.g. 8 chips + 4 parity chips),  they are
considered 36bits.  This motherboard sums the memory per bank and therefore two
modules will give 72bits and the following will be displayed:

If your DRAM modules do not have parity chips (e.g. 8 chips),  they are considered
32bits and the following will be displayed instead:

The default of Disabled for Memory parity SERR# (NMI) will not show memory
errors on your monitor.  When using parity DRAM modules, you can select from the
default of Parity or ECC (Error Checking and Correcting) to correct 1 bit memory
errors that may occur in the memory.  See Section III (Installation) of the baseboard
user’s manual  for DRAM memory modules information.

Onboard FDC Controller
When enabled, this field allows you to connect your floppy disk drives to the on-
board floppy drive connector instead of a separate controller card.  If you want to
use a different controller card to connect the floppy drives, set this field to Disabled.
Default setting is Enabled.

Onboard FDC Swap A: B:
This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Two options are available: No Swap (default) and Swap AB.  If you want to
switch drive letter assignments through the onboard chipset, set this field to Swap AB.

Onboard Serial Port 1
Settings are 3F8H/IRQ4 (default), 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
abled for the onboard serial connector.

Onboard Serial Port 2
Settings are 3F8H/IRQ4, 2F8H/IRQ3 (default), 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
