Re: [Patch] Compaq LTE

it's just a simple generic patch to see if Compaq LTE can run with a minimum code in PCem. its hard to write a complete patch for a whole single machine, especially from scratch. Didn't the Compaq LTE use a blueish grayscale CGA display with 4 shades of gray? The Compaq LTE 286 did use a grayscale ...

Re: [Patch] Compaq LTE

Didn't the Compaq LTE use a blueish grayscale CGA display with 4 shades of gray? The Compaq LTE 286 did use a grayscale VGA display with 16 shades of gray also. It's been mentioned a lot everywhere. :p

Re: SCSI roms

I would strong advise against asking where you can find the SCSI ROMs that you do not legally own. If you have a real ISA, VLB or PCI SCSI adapter and have a dumped a ROM that matches the supported adapters emulated in PCem. Don't even think about trying to ask for copyrighted ROMs in the forum, mor...

[REQUEST] IBM 8514/A & XGA adapters

When IBM rolled out the Personal System/2 launch models 30, 50, 60 and 80 on April 2, 1987, these models had a integrated VGA chip. When VGA was introduced, IBM also introduced another display adapter, the IBM 8514/A . The 8514/A display adapter offered 640 x 480 pixels @ 256 colours and 1024 x 768 ...

Thank you for reporting this. I've also reported that the floppies don't work at all on the PS/1 Model 2121 as well.

All the Cirrus Logic cards, both the Mach64s, all the S3 cards, the ET4000/W32p (Diamond Stealth 32) and the Trident TGUIs. UNIVBE should be able to enable LFBs on all of them.

You might also have to use a newer graphics card that supports linear frame buffers.
That sounds like a good idea. :)

Does anyone have any idea which ISA and PCI graphics cards support linear frame buffers? Just curious to ask.

Happens on real hardware - VGAPaint looks to have buggy VESA 1.x code. It works with UNIVBE loaded, though you will have to delete the INI file so you can reconfigure the video mode. Thank you very much for telling me. I'll have to go for UNIVBE instead of UNIVESA. :) EDIT: Sarah, I tried UNIVBE an...

I get the hang on the same mode on all the Cirruses at least, on the Trio64 (which DOSBox's default is based on) and on interpreter so it doesn't seem to be Trident-specific. I'm with you on the same boat here. EDIT: VGAPaint 386 does work with a PS/2 mouse. VGAPaint 386 is broken on serial mouse a...
