I saw today that you are looking for a manual for the Acorp 5VIA3P motherboard, I have a motherboard with a MII 333 (3.5X75), if I remember correctly I have a 128MB dimm, but if you are interested I can restart the PC and provide more info.
Unfortunately I don't have the paper manual for that card, but in the link there is the online equivalent (images), I don't know if it has already been inserted previously, I hope it will be useful, regarding the BIOS the latest version available is not correctly recognizes the fastest CPUs, both MII 300 and 333 are recognized as 6X86MX 266, a mod would be needed, unfortunately I'm not able to do it, and I don't know if anyone wants to modify the BIOS, for those who would like a BIOS that correctly recognizes the installed CPUs, unfortunately in that motherboard there is no possibility to select lower voltages for the VCore, but by finding a way to lower the VCore you could also install a K6-2 400 (or more) , selecting 2X that the CXT remaps to 6X, then if 400MHz is not enough you could select 75MHz FSB, thus reaching 450MHz, 500MHz with 83MHz FSB is also possible, but I'm pretty sure the PCI will go beyond 41MHz, and here they could there be problems with the hard drives.

Thanks! But I mostly solved all of the issues that I was dealing with, during the discussions in this thread.
That's not to say that there aren't more unknowns regarding this board... But for me, at the moment, the board has done it's job as a temporary testing rig 😀
I already posted these pictures along with maybe some other useful stuff, in the archives in this post: Re: Acorp 5VIA3-P - MANUAL needed, pls!!

A full manual would still be great though 😜

Please I hoped to be more helpful, unfortunately I don't have a paper manual of this board, and I don't know how it's done, it could be very simple (a few pages), as it could be very detailed, I don't think you can find it, maybe it could have that who put the images of the link I put, we should see if you can contact him and ask him if he can provide the other pages.
In the future if I can make a mod for the Vcore, without soldering anything to the motherboard, and it works, I might drop the voltage from 2.8V to 2.2V, but I don't know if what I have in mind will work, in that case (i.e. if it works) I could install a 400 or 450 Mhz K6-2 CXT, using 2X multi (remap to 6X) and FSB 66 or 75, I don't think to go to FSB 83 (500MHz) because the PC becomes unstable.
If you succeed, the last thing that could be useful is a modified BIOS version, if you manage to get the VCore to go below 2.2V, you could also install a K6+, here if you are interested there are many motherboards with modified BIOS : http://web.inter.nl.net/hcc/J.Steunebrink/k6plus.htm
