Re: SVGA/VESA programming
Posted on 2022-06-21, 18:08
in its time, vesa was not really a thing on 286 VGA cards, so I've only ever done VESA programming in pmode using the linear framebuffer. bank switching is just a pita and slows things down. since your not targeting a 286, not using the LFB seems like punishment :) I'll have to dig around, I have …

Finally got the motherboard out of the casing, here's a detailed photo of it. I also got the new voltage regulator in the mail yesterday so that means this board will finally have a voltage regulator rated for 7 amps! twice the current is asking a LOT from the motherboard. I dont see the point, but …
Re: Does this USB solution/thing still not exist?
Posted on 2022-06-15, 15:21
Is this even possible, or am I overlooking something. And if it is possible, but none are available, then how difficult is it to make one? well, you would have to intercept every usb pack going to device, hope that it was class compliant device so you could understand what is in the packet, detect …

it depends what the developer of program X says it needs. otherwise you'd have to analyse down to the opcodes to see but even then you dont know the execution path and some app could have 386 opcode that never use them if its on a 286.... so... no... you cant tell.
Re: Trying to write a TSR to extract the VGA palette. It works, but can cause DOSBox to freeze. Need help to fix this.

Also, I looked it up and I believe you're confusing the behavior for DI with how it is used by byte string based instructions. (movs, insb, outs, stosb, etc.) Why don't I use insb and stosb? Don't I need to specify the color index at 0x3c8 for each palette entry? its been a while. maybe I was …

line 27, your not closing the file you think your closing! moving stuff into DI, you need ES, you only setup DS. DI uses ES by default. also you could just mov cx,0x300 l1: insb stosb loop .l1 also dont call the redirected interrupt via an INT call, just jump to its address.
Re: DOS file size limit
Posted on 2022-05-16, 16:38
This is interesting, as the last DOS compile of 7zip archiver (v. 16.02), *does* work with and extract files of up to 4GiB -1 in native, unpatched, baremetal "DOS 7.1", and it appears to set the "extended size" flag. However, it also works with such files on FAT16 drives with 64kb cluster sizes. …

since this isnt a pnp card, did you set the jumpers correctly to not clash with other existing IRQ + DMA on your other cards? These are the reasons for it hanging.

Re: Split-channel MIDI setup: CM-32L cluster (64 voice polyphony) & SC-55 cluster (48 voice polyphony)

does it actually renumber the channels on split, so you said odds, evens so like 1,3,5,7,9 becomes 1,2,3,4,5 on device 1? the screenshot of the sc55 displays seems like this is not the case, so your not actually doubling the channel count, so seems kind of pointless. you could just run a midi …

yes. you cant write different sized images to disks like that. 180kb had 9 sectors per track, 40 tracks, 1 side. 1.44mb is 18 sectors per track, 80 tracks, 2 sides

sounds like your writing a 720kb image to a 144mb image or so.
Re: Does DOSBox support changing the code page? (EDIT: nope not by using int 0x21 - The KeyB command does work however)

tr179 isnt a dos code page. so I dont know what you want. dosbox-x has no 857 codepage (in my nightly build), which is weird but, keyb us 857 would work if 857 existed...

Re: Is a Roland SC-55 Okay or do I need a MT-32 ?
Posted on 2022-04-18, 18:36
I'd say, they are distinct form each other. SC55 has the MT32 instrument list but its not MT32 compatible. MT32 has much deeper programability/functionality that is not replicated outside of MT32. Those roland devices like SC55, SC88 that have an MT32 mode doesnt mean much if the game is going to …
