Unsure if this is the right place to put this post, but if not, Sorry 😁

I am currently building a Pentium II 266 MMX based slot 1 system, with a Cezch(i think?) made motherboard which i believe to be the ASKA SST-5721
It's an ebay purchase, using it because it came with the I/O shield and ticks all the boxes AGP slot PCI slots, ISA slots, IDE/ Floppy, Slot 1, ATX form factor, SDRAM support and Intel I440BX chipset

So basically I'm looking for the manual, can't seem to find it online anywhere, Does anyone here know this board or have the manual?

it's only seeing 64mb of ram (known good memory) of a 128mb stick, and has an annoying standby feature when power button is pushed that I'd like to disable, there's also a few jumpers which are not labelled / not labelled too well on the board.
