As it turned out i need to buy a new motherboard after all, because none of my com ports seems to work on the current board

I suspect weedeewee is correct in suspecting that you might use the wrong type of cable. But even if the com ports are completely dead, you can still use the board with a standard AT multi-I/O board in one of the ISA slots. Just make sure to disable conflicting components either on the main board or on the I/O board.

He mentioned they were working before, so unless he switched cables somewhere, I doubt that it's the cables.

Unfortunately its not the cables… if you read back my comments ever since than i brought an other main board and the ports work with that board with the same cable. Also now the at keyboard port szopped working so slowly it get broke port by port.

I mean, you don't have a problem at all with no cache chips installed? (data sram + tag sram)

Well i didnt take out the chips physically, but if i disable extended cache in bios it boots no problem. But it still doesnt recognise the cd rom drive. So that could be a different problem.

Thank you. Have you got your serial mouse running? I'm sad your board offers no PS/2 mouse connector. […]

Hey i managged to do the test heres are the resaults :

Thank you.

To your benchmark results.
Yes, they look very like unoptimized default values. In a 486 optimizing them makes a huge difference!

Hey.. Finally i managed to get a motherboard with working com port.. so it seems everything works now.. so i wonder how could i optimize the cache ? Could you help me out with it?

Sure. May you post a picture and a screenshot of the POST too?

Hi i am not quite sure what you mean by post screenshot, this is my best gues xd.. anyway i rerunned the cache test as well with the new mobo.. i got quite the same resoult.. here are the pictures

Thanks. I prefer to see the SpeedSys graphical cache chart for diagnostics.
And perhaps you can make a screenshot of the BIOS, page "Chipset Features" too.

May you post them too please?

Oh, there are a lot of settings subobtimal.
Just change 2-3 settings and run Quake/Doom from DosBench suite to basic test stability.
Look to the memory chart and compare it to previous runs.
-

L2 Cache Tag Bits does not match to your Write Back selection. Pick 7+1 instead
(Then test floppy access)

The 3 Cache settings could be set to minimum.

Play with the DRAM settings too.
At 33 MHz FSB you may try to set them to minimum, but read setting (RAS to CAS delay) may be 1 above minimum.

You can play with DRAM speed to fastest (at 33 MHz FSB)
ISA Bus clock should be at 1/4

I set CPU burst write, but I do not yet know in which cases it works.

IDE Prefetch read buffer Enable

Thank You i will play around with the values.. is there any option that could kill the board or cache chips? Or i am free to set these settings in worst case i just has to clear cmos?

You don't need to clear CMOS because those settings are applied after POST.
With 33 MHz FSB and those waitstate settings, no hardware damage expected.
However, your system may halt / freeze if settings are too aggressive. Those freezes are likely to occur either quick or in some situations only, like games with sound output. DRAM read waitstates are a candidate, when optimized to aggressively.
In the worst case you may have corrupted files on your system, but it seems to be unlikely with your system.
