Thanks for your fast reply! Now I'm just wondering what memory modules to order from eBay 😀 If i want to add 1mb then I need two 32K x 16 modules or 64K x 8 modules (That I can't find in eBay) ? Or can I throw in bigger modules like 256K x 16 ? Or am I missunderstanding something?

Hi, It's me again with my newbie questions :) I have couple of Trident TD9400 and I'm looking to update the memory. I think the maximum amount is additional 1mb (2x512 to the free slots) totaling 2mb? Does anyone know what memory modules are suitable for this card, does all SOJ-40 packaged DRAM's …

Thanks! Now i'm just wondering what E/EEPROM programmer to buy 😀 any tips? Also why do you recommend 32-pin in favour to the original 28-pin? What come to the BIOS chips, could you also advice what are suitable 28 and 32-pin chips?

Hello Gents, OK, so I got myself a POST card, this is the result. It wont show any codes, i tested with other mobos and the post card is working. Any tips? Filename postcard.jpg File size 208.69 KiB Views 1160 views

I tried to remove the cache and also tried with an other BIOS module from Shuttle HOT 419 (it has also a OpTi 895 chipset) but it didn't work. Maybe i'll just scrap this mobo? You shouldn't scrap it, 486s are not that common to find. Put it in storage, it will find its use one day. If you need a …

Do you happen to have the QDI V4P895P3 SMT V5.0 BIOS ROM still available? just got this board and I think the BIOS is defected (won't post, tried everything else and measured VCC:s etc.)

Great! It means that the voltage regulation is working. I would suggest you to configure the motherboard using the second manual and a 486DX or 486SX (at least for now). No DX2 or DX4 stuff, just 486, 5V. Tried with SL - DX486 jumper settings, doesn't post :/ v4p895p3-3-DX.jpg OK, so no progress …

OK, I made the measurements! :) With 3V jumper setting (JP1 open) I get 3.469V from VCC legs and with 5V jumper setting (JP1 closed) I get 5.094V-5.115V from the VCC legs. Great! It means that the voltage regulation is working. I would suggest you to configure the motherboard using the second …

I am quite sure, that both manuals that you attached, do not match 100%. So ignore it, and use as only reference the writings on the board. The second manual seems to match his board, what makes you think it doesn't? All jumpers seem to be in the same position and markings as in the manual. True, …

About the voltage regulator, should't i get out something with DX processor (5V) jumper selection? The voltage regulator will get bypassed in 5V mode (in this case the CPU is fed power directrly from the PSU). It would be a good idea to probe the voltage from the CPU socket directly (when there is …

I assume the voltage regulator is bypassed with the 5v jumper. I tried with a AMD 3V processor and 3V jumper settings, I get in 0.8V and out 1,5V Can you make a good picture of the area, where the voltage regulator resides? Here are more pictures of the CPU area. v4p895p3-2.jpg v4p895p3-1.jpg

lol, i means internal here. So you put 50MHz to the poor DX2/50, no wonder that it heats up, it can't run at 100MHz. But that the Intel DX 33 does not heat up at all is very suspicous. EDIT: For the case of Intel DX33, the voltage regulator should not play a role, but maybe it does (?) Shit :D your …
