Yep, before the time of resizable BAR, GPUs stick to the PCI standard of having a max of 256 MB mapped address space available. So Windows XP is technically fine with having more than 256 MB of PCI device memory because the standard doesn't allow for more anyway. However, it is the responsibility …

I don't think 32-bit Windows XP can even address 4GB of VRAM?

In that case, assuming the board has an AMI Bios, 0E is sending the BAT (Basic Assurance Test) command to the KBC, and 0F is initializing the KBC after BAT. That means there is probably still a broken trace that stops the KBC from initializing. Check that the KBC is actually connected to the …

I find upscalers pretty terrible at handdling anything fast moving. I tried watching a Disney cartoon on DVD with my daughter month ago and it was terrible. Switched to Disney+ and the 4K image was uncomparable..

Interesting. I'm the exact other way around, DVD resolution on a big screen is unwatchable for me, but I can tolerate 1080p on a 27" display at work..

For the longest time I thought 1080p was enough. Then I bought a 75" 4K MiniLED TV and I can tell you at this size 4K matters. For desktop, I am OK with 1080p up until 24". Beyond that, I enjoy 1440p considerably more. I've never really been able to tell 1440p and 4K apart on a monitor.

QEMM was indispensible in the MS-DOS 5.0 days when DOS's own memory management was kind of mediocre. Startup menus and QEMM being one of the options was almost necessary to be able to run some games at all.

I have seen many 286 boards fail to POST without battery power. Try to add a new battery and see if that helps.

Well, I have reflowed the DAC and then all the electrolytic SMD capacitors in the area, but that did not help. That leaves me thinking maybe one of the untouched but oxidized smd capacitors in the vicinity is the problem, so I will reflow all of those later this week. I haven't put the oscilloscope …

The performance ratings became more inflated over time. The 1900+ (which I had back in the day) ran at 1600MHz. The 2500+ (which I had later) ran at 1833MHz. How does a mere 233MHz increase translate into 600 marketing points? Increasing cache and bus speeds mitigates memory latency but it doesn't …
