VGA1 video adapter problem

I have been trying to refurbish an old model pc (xcel-2000, pcchips M748LMRT) using a slot1 Pentium II processor @450MHz, but there is no way I can get the video adapter working, so that I can configure the BIOS settings. The manual for this mobo says it should used at least one pc-100 MHz SDRAM memory on slot 1 for the video to work, but I don't have a pc-100, instead I am using a 128 MB, pc-133 MHz memory, but the VGA1 video adapter (which is connected to the motherboard) does not work.
The manual for this motherboard can be downloaded from here:
Please, any help will be greatly appreciated,
Thanks in advance,

Re: VGA1 video adapter problem

The MB supports both PC100 and PC133 RAM. Make sure the RAM Module uses LOW Density Chips (16Mx8) Technology. You wont get video or even be able to POST (Power-on self-test) with latest high density modules.

Re: VGA1 video adapter problem

Make sure you have a PC100 memory chip in the DIMM #1 slot or it can't use that memory .

Your motherboard does not support PC133 memory.

Re: VGA1 video adapter problem

The Problem could be that the BIOS setting for the shared video memory is set to "disabled". You can fix this by either 1) install a PCI video card temporarily and then making the change to the BIOS to shared memory "enabled" or 2) clear the BIOS settings using JP5 on the motherboard.

Hope this helps.

Audio driver for Xcel 2000 motherboard

I think the Xcel 2000 was made by PC Chips. It could be PC Chips model M748LMRT, but not really sure. Do a google search for the PC Chips M748LMRT to find a pic of it to compare with your brother's board, then find a driver site where you can download a driver.


Hope this helps,

On these old motherboard there is usually one switch that is used to change the CPU type - from Slot to Socket, in this case. But there are usually a different set of jumpers that control the CPU speed. And usually another set to control the bus speed, assuming it supports more than one. In this case it might support 100 or 133, depending on the CPU.

In some cases, you can set the jumpers to "AUTO", which automatically selects the bus and CPU speed. This was only available on the higher end, newer and more expensive boards.
