Great, thank You all for informations. Maybe somebody else will write something about jumpers on this Cirrus Logic combo card. I think that I have to find some motherboard in my collection with these UMC chips and with known jumpers settings and then trace the paths from jumpers to chips. How do …

You could try ventoy. or get something like the zalmen ve-300 or iodd 2501 if you can still find them.

I have a bit of an odd question: Is the PicoGUS compatible with Linux? Especially some older versions from, like from 25 years ago. I know that there was quite extensive support for the GUS back then, including MIDI and patch loading, etc. I don't think there is a compiled binary of pgusinit for …

funny, considering it mentions top view under the pinout in the pdf, I would think it's VLDT0_A (B 29) scrap that AJ2 MEMDQS(2) seems more correct.

Then there's no other option than that it has to be a board problem, either a cut trace, bad solderjoint, bad logicchip, ... on the multi io card where com2 isn't working.

I have a very similar 50pin header for optical drive on a DigiPOS compact point of sale PC. Someone on the thread for those systems tested the pins and concluded that the extra pins beyond 44 aren't actually used, and a normal 2.5" IDE 44pin cable would work! Sure enough, using a 44 pin cable, …

just a guess, Try C/H/S : 1024 / 16 / 63 if the C: drive error is gone using this, you should be good. if it is still there, you 'll need a different solution.

Ok I'm back to my issue... Finally took the time to take more pictures. I was wrong when I said the cable was sealed in the plastic, in fact the internals are fully exposed as you can see... The part number says 135233-001 . 20240524_224836.jpg 20240524_224841.jpg 20240524_224852.jpg 20240524_ …

wouldn't it be possible to remove the dos version check from sys, and use that to write the bootsector and other files(io,msdos,command) to disk ? Seems easier to do it that way or if freedos has some functionality like SETVER , use that

Will this be available in a PCMCIA form factor? Last time I checked, Freddy doesn't have PCI, PCMCIA, VLB, or even 16 bit ISA in his plans at his time. Oof, that sucks. AFAIK the PCMCIA standard is just an ISA slot. EDIT: If the schematics ever get released, I may look into that. EDIT TWO: It is a …

Note that when this is connected, that is no longer a parallel port at all, and the pinouts change. It's worth checking the cable itself for damage inside the connectors; it may be missing something that tells the computer to change the pinout and put 12V or 5V on some pin to power it. It …

I tried and no it does not work. Dangit, I was hoping it would work out of the box since I'm fairly certain on later model compaq m700 it actually does work, though I would have to check to be 100% certain. I guess a driver of some sort will be required for these older machines, although since the …
