9. Connecting ATX Power Cable
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. The
blue connector
is IDE1 for clear identification. Be careful of the pin1
orientation. Wrong orientation may cause system damage.
This motherboard has two 168-pin DIMM sockets that allow you to install PC100 or
PC133 memory up to 1.0GB. The MK33M / MK33M(A) supports not only SDRAM but
also VCM and Registered DRAM.
DIMM1
DIMM2
Tip: The driving capability of new
generation chipset is limited due to the
lack of a memory buffer (to improve
performance). This makes DRAM chip
count an important factor to take into
consideration when you install DIMMs.
Unfortunately, there is no way that the
BIOS can identify the correct chip count;
you need to calculate the chip count by
yourself. The simple rule is: By visual
inspection, use only DIMMs that are
less than 18 chips.

Attach the power LED, Keylock, speaker, and reset
switch connectors to the corresponding pins. If you
enable “Suspend Mode” item in BIOS Setup, the
ACPI & Power LED will keep flashing while the
system is in suspend mode.
Locate the power switch cable from your ATX
housing. It is 2-pin female connector from the
housing front panel. Plug this connector to the
soft-power switch connector marked
SPWR
.
The ATX power supply uses 20-pin connector shown below. Make sure you plug in the
right direction.
