M748LMRT mobo won't start with ATX power supply
I've been trying to refurbish an old computer with pcchips M748LMRT-xcel 2000 motherboard. The mobo manual states it can use either an AT or ATX power supply. I only have an ATX 230 watts power supply. When I assembled the mobo on the AT case and plugged the ups cord in the ATX slot, the computer does not start at all. I downloaded the manual for that motherboard from this site:http://mldisplay.com.br/m748_v13.pdf.
Since I could not longer use the power switch because it is designed for the AT power supply, I used the RESET switch as the power switch. I connect it on the right pins on the mobo, but NADA, it won't start.
On the manual it also says:
If you are using an ATX power supply unit, you can use hot keys
on your keyboard as a power on/off switch for the system Use this
jumper to turn this feature on or off.
I set the specified jumper to enable that feature, but it didn't work.
The cpu type is Pentium III 450Mz cartridge at 100MHz system bus.
Memory: 128 MB SDRAM/pc100.
Can somebody please help me with this issue.
Thanks a lot in advance,
Osmany
