Do video cards have these on? I could desolder some. Until tomorrow, I'm going to bed.

I made a mistake. The motherboard has 43 pins per side for the SDRAM chips. Ram sticks have like 28. I need to locate specific sdram chips. I don't know if this operation is ever gonna see the light of day. Could it be L2/3 cache? ARchive has 3DMark 99 files in its extension, .3dp

Screen 800x600, 1024x780, 1280x1024, 1600x1200 16+32 bit colours I thought much worse. Now I have something to compare to if the dedicated ram works.

I'd suggest to try something older then: detonator_3_w9x-805 or nvidia_9x_5.32 I checked the inf files bot supports the Aladdin TNT2 You were absolutely right! I used ver 6.18 as I couldn't locate 5.32's agp166 file in dirver archive (got from phil's). Now it works. Gonna do the whole test batch.

I had to uncheck the first two tests, the rest is just displaying garbage on the screen, but it does something. From time to time it shows % bar. 🤣

I had a similar issue and the answer was either to just put a solder blob or a 5µH smd.

Does anyone understand where pin 1 is located? Before I solder everything the wrong way 😀

The 32MB video RAM refer to to the shared main-memory here, I´m afraid. video_ram1.JPG You can populate 1GB main memory, the onboard graphics will grab 32MB of it as shared memory. This is just a tiny bit of 1GB. I think it´s not worth the effort populating the two RAM chips onboard for an …

The max IDE config without going to extremes that might be got with mainstream hardware from the mid 90s, would be primary and secondary IDE controllers with 2 drives on each (Maybe on one superIO, VLB or PCI or onboard) and tertiary controller on a soundcard that can be set to IRQ11 or something, …

2M*32 makes 2x8MB chips. I have to take 2 from a 64MB ram module. Question is: are they gonna get detected? Guessing no modules are detected it goes to shared ram, if present no sharing.

Found the manual! Reading this I presume I can solder 32MB of sdram to have a max of dedicated ram for the graphics card alone, not sharing with main. Gonna try that. Probably PC-133 should work great as the GFXPro ( chip comes with a PC133 writing on it. :) Goes as Amptron 3754 Edit, it'd at …
