There are a few archive sites but you'll need to find the machine type-model label on it somewhere.

This covers several models, maybe yours is in there... http://ps-2.kev009.com/basil.holloway/boo-to- … 83G_7789_08.pdf

Ok i found the manual. There are some undocumented jumper than can set the fsb to 16-20-25-33-40-50 mhz..very well but… no cyrix, no amd, no pod works. And i have not even found a way to set the cpu voltage, all the test are still done with the original regulator for the DX4 installed.. can you help me a little bit more?? about the voltage, about the bios for amd and cyrix (i think that the pod will be a lost battle)… tnks

AlessandroB,hello there.
Can you post here or PM me photo of your motherboard and photo for DX4 regulator.
Couse looks like i have headache with similar mobo from IBM.

Hi ApostolCV , I found your post and i reply directly there, also because I have the regulator ... but you have the bridge I need for the 5v..go to check
