It's being screened. Don't ask. *shrug* In the meantime I continued playing with settings and found that the purple color corruption could be fixed by forcing 16-bit color mode. The weirdness with animations was a fun one. If you run the game with Windows set at any resolution above 1024x768, you …

*shrug* I don't know either. Work policy thing. I'm just working with what I'm allowed to do, so basically I'm stuck trying to make the original game work and not a more modern modified/patched/updated/downloadable version. To answer your first question though I tried the 5-disc version and it had …

Technical limitation. I've never used SCUMMvm and that would be another thing I'd have to get approval to use. Something like DxWnd or DDrawCompat I might be able to get away with saying it's a supplement component.

This is a bit of an arm twist, but I almost got it. I have a Windows 10 system that spends its entire life testing touchscreens. It makes sense to run something like a point and click game for testing and Riven is still visually pleasing. My restrictions are hard-set that the machine is non- …

I built up a Packard Bell FORCE 480CD system and had a spare Packard Bell OEM 2320 PnP card available so I put that in. The correct Master CD for this machine is not expecting this card (it wants a 2316) and installs the wrong drivers which do nothing. Digging around I have the Master CD for my …

My only exposure to CPU's emulating other CPU's was the Transmeta Crusoe. A general purpose CPU that depending on which microcode was loaded could emulate virtually ANY cpu.

Okay yeah, grabbed two known PC100 128mb sticks and tried to make it fail POST and the problem went away. So either the BIOS is trying to make it run a memory frequency it can't support or something else is unhappy about the higher speed. Performance isn't a big issue here though so I'm happy.

Yes, made a mistake there. Looks like a PC100 stick got mixed into my PC133 bin. To clear things up I just tested it: 1 x 256mb PC133 SDRAM = One-time post, then memory error beep after reset 1 x 256mb PC133 SDRAM, configured in BIOS to run at PC100 = Reliable POST 1 x 256mb PC100 SDRAM = Reliable …

The sticks I have say that they are rated for PC133. I have not popped the heatsink off but it seems to imply it's a 1Ghz PIII with Tualatin's telltale top heat spreader. THOUGH now that you mention that I noticed the fail-safe forces PC100 mode and the system seems to run reliably at that. Its when …

I'm building a disk imaging station and assembled a system around a PEAK 650 Socket 370 SBC board.

No it's just down there where it can't be found.

The modem uses a "secret" PBX extension so from anywhere inside the building and …

Had a floptical drive for a Silicon Graphics Iris Indigo that wouldn't read floppies. To test if it was the special Teac-chipset SCSI to floppy bridge or not I haphazardly plugged it into another machine with SCSI but didn't observe pin 1. Fried it. I've never seen a SCSI device fry like that before …

maybe that particulare '151 is faulty after all. I really dislike desoldering stuff from mobos, because sometimes the old traces/vias get damaged and there's even more stuff to fix, but with no other tools and ideas I would try to desolder this '151, and the other one that has IRQ12 connected to it …

Oh well. Let's dig deeper into this. See if /E input of the '151 (pin 7) is connected to chipset or tied to GND permanently. It is tied to ground. est inputs S0,S1,S2 (pins 11,10,9), you should see them toggling. All the time actually to properly scan all inputs, unless this chipset is "smart" and …
