don't think I can help much but this looks like the same motheboard that my Compaq Presario 7583 had,
also I think the following series (5000?) with a different case design also used it.

the motherboard from the same period used on the k6 version looked similar and was made by Mitac, maybe it's the same manufacturer,

Good news is that it is a pretty standard socket 370 matx mobo. i810 chipset, a solid 4 pci slots (very handy) and SHOULD be support to at least all 133mhz fsb and lower 1ghz +/- processors. You can run any number of good early pci based 3d graphics chips, for example SLI voodoo 2's and a lan and audio card. Solid system, I used a similar Dell for a friends compact 9x pc. If you can trial and error a power on signal to the front panel connector you should be good. If it is like the dells it should be fairly standard.

Theres no problem trying find the power signal?
The board feature ESS allegro. Dont sound like the Solo-1, but at least is not a CMI.

A steady hand and a flat head screw driver should be enough to find the power on from the front panel jumper pins. Look up the standard ac97 atx era intel config, and if it isnt what that says for power switch config, then start jumping different front panel pins horizontally and diagonally. While properly grounded of course.

I found this manual?

This one is the closest besides the header position and chipset (815).
