If it boots in safe mode... You might also try either the 2gb+ ram patch (even though you have 500mbyte), and or, edit system.ini to exclude the adapter rom region from being managed by vmm. https://archive.org/details/PATCHMEM http://tinas-sliderules.me.uk/Msconfig.HTM If there is something that …

Cpu speeds over a certain value, and amd chips after k6-2, are known to have this happen. There are patches to fix this. https://github.com/JHRobotics/patcher9x

Not surprising at all. the OPL chips are very well documented (and dont have super secret sauce inside them like a SID chip), and the secret sauce that soundblasters DID have for their DSP chips, got successfully dumped using side channel exploits over the years. There is even a thread here on …

With most RAM configurations, the data and address lines are conserved, and individual chips respond when the chip select ( CS ) line is raised. So, if you just stack them up like dead bugs, and bend the CS lines out, and put bodge wires on leading to the appropriate leads from the DRAM controller, …

It comes from the DOS limitations on partition size for FAT16, which is 2gb. In addition to that, there is the baseline CHS limit, at 504 mb. Normally only seen on some really old 386s and older. Then there is the modified CHS limit at 8gb, Higher than this, DOS cannot address the sectors since it …

I've used it with war2 before, set it to 8bit soundblaster compatible with generic opl3. It hates sb16. The music volume does odd things when pcm audio plays though.

'Taking forever to run a dir command with lots of free space' is a thing that's been seen on real hardware before. Disk caching REALLY helps with that. One thing to consider, if the driver for USB sticks wants raw formatted, would be to format the rsw block device (and not a partition) with linux. I …

Define "SuperVGA", is what I would ask. 256 color mode X was used almost exclusively in the period in question, as it could be supported on "Basically any" VGA card, and gave a decent viewport, good color depth, and could be drawn fairly quickly/easily, with true 8bpp framebuffer. LOTS of games …

I found a win7 x64 driver of dubious providence for this chip... but as it is dubious providence.. :( The 'official' statement from intel is/was "no" for 64bit os on this gpu. That said, you might try looking in dell, toshiba, and ibm/lenovo driver archives. Sometimes bespoke versions of the driver …

wierd_w , I fully agree with your point. My current SBEMU on CMI8738 test system does not have any PCI or ISA NIC adapter installed, so I decided to use interrupt 5 over 7 for the SB16 emulation as it is completely free. If I add some NIC adapter I may switch to default interrupt 7 for the SBEMU. …

Iirc, 'normal' low dma is 1 or 3, and High dma is 5 or 7. Irq 5 or 7. It has been awhile though.

For the record, It was abundantly clear to me that JEMM is not aiming to be an EMM386 clone. It does not report the same EMS handler name, and does things quite a bit differently than EMM386, presumably with an emphasis on "Doing things better, and not being constrained by legacy behavior" If you …

It very well could be the same int10h issue being discussed. Int10h is invoked to tell the graphics card to switch modes, based on a value stored in register ah. In the 'for realz, THIS is causing a loop! da fuq!?' Example cited, the code is basically saying 'put the value 01 into register ah, call …

Also called UniVBE, Scitech Display Doctor is a universal vesa bios extender for a great many period accurate video chipsets, since it was hit and miss on even having a VESA driver, or having a VESA driver that did not have showstopping bugs (like your apparent INT10h loop bug.)

Does loading scitech display doctor fix it? This thing presumably has a real vintage chipset, so it should detect/use.

Hello, I am new here. I just got my pocket 386 and my impressions so far: The screen is only held by 2 screws instead of 4 like the book 8088, so the screen's upper shell is loose because there are no screws to hold it in place. Mine comes with the right speaker rattling, so I just disconnected the …

I read about the problems with port trapping with addresses lower than 100h with EMM386.EXE and maybe the best solution for compatibility will be some patched EMM386, but this is forbidden topic here. I don't see why it's forbidden, to modify a proprietorial program? It's not necessary to modify …
