(Chipset Features)

[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 pages 12-13 for more information on
DRAM memory modules.)

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 “Dis-
abled”. Default setting is Enabled.

Onboard FDC Swap A: B:
This field reverses the drive letter assignments of your floppy disk drives in the
Swap AB setting, otherwise leave on the default setting of No Swap. This works
separately from the BIOS Features floppy disk swap feature. It is functionally the
same as physically interchanging the connectors of the floppy disk drives.

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