Hi. On an IBM PC 350 Pentium 75Mhz machine, is an embedded S3 Trio 64 chipset with 1MB video memory. It also has 2 sockets for upgrading video memory to 2MB. So I took 2 memory chipsets from a working 2MB stand-alone S3 Tri 64 PCI VGA card, and shoved the suckers into their slots on the IBM mobo.. but nothing happened.
BIOS still says I have 1MB video memory, and trying to use higher resolutions in Windows 3.11 fails with out-of-video-memory error.
I looked around for any jumpers that would tell the system about the additional 1MB video memory, but couldn't find any.
Wondering if I missed anything or if anyone did this upgrade before.
Here they are in their new slots:
Also wanted to mention the standalone card was successfully using all its 2MBs without issues or corruptions, so the chips extracted from it should be working.
