DOS CDROM stuff is all PIO, so AFAIK being DMA capable or not shouldn't matter. I haven't really tried to formulate a theory of my own yet, but I would lean toward a software limitation or bug either in VIDE-CDD or possibly the EMS driver itself

Good point, I was somehow fixated on DMA . I must still be low on caffeine, 🤣 .

I'am pretty sure thats incorrect. Just look at the Bus Master driver package from Triones for Intels Triton chipsets.
Or adaptecs CD driver for their scsi cards, or early CD-ROMs with proprietary connector.
I attached some readme from the high speed cd-rom driver bundled with a Lite-On CD-drive.

Fair point. I should have specified on
pre-PCI systems

Good news! I've found a tiny CD-ROM driver that is smaller than Vide, can be loaded high and is from Microsoft! 🙂

Edit: Also worth a try is cat.com, the quickest mice driver in the world.

It would be good news for all of us if you could share said driver 😉

Please do let us know what you are referring to . I hope it has nothing to do with being either loaded or high in any context other than than of a UMB . 😉

Do also let us know if you are feeling alright .

Sure, I do! Do tell you. At the moment,
nine of ten voices in my head are saying that I'm nuts, whereas the tenth is humming the melody of Tetris (Type-A).. That's fine, I really like Tetris.👍

Enjoy your mental polyphony and, if you can expand it, then maybe that tenth voice can find a virtual balalaika to accompany it .

Cheers!

Sure, gladly. 😁

PS: Simply run it with CAT /5 for maximum speed..

I might have to once again correct my findings about VIDE-CDD. Loading it low may have been a red herring in my case, I am still having issues with this particular system.

EDIT: Yep, even when VIDE-CDD was loaded low and the EMS driver was NOT loaded the CDROM was still having issues. So I physically removed the EMS board and loaded VIDE-CDD high again, and all is well. So the issues really were from a hardware problem with the EMS board in this system. The CDROM works perfectly now with VIDE-CDD loaded HIGH!

Hm. Could it be that Vide-CDD somehow conflicted with the EMS page frame then ? Or something along these lines ? 😕
I wonder, what would happen if another EMS manager like EMM286/3MM386 was in charge ?

No, when the driver is not loaded the card does not have a page frame. It's software configured.

Again the card simply being in the system was breaking the cdrom, regardless of where VIDE-CDD was loaded in memory

Ah I see. Didn't know that, assumed the EMS frame was perhaps set via DIP switches somehow. 😅

Hi, did the drivers work that I posted a while ago ? - I'm curious. 😁
I've got a few more on older diskettes. If there's a need for them, I'll make a copy.

your posted CD driver is labeled "Microsoft CD-ROM Driver, Version 1.1"

I found this piece of information here:

Show full quote

CD-ROM extensions
Microsoft CD-ROM driver versions 1.0 through 2.0 will
work only up to DOS 3.31. DOS 4.0 and up require 2.1
drivers. MSCDEX abandons INT 13; and redirection
within DOS to do its work. Some LAN software, such as
LANtastic, uses the same mechanism to implement
network drives. MSCDEX provides IFS functionality in
any version of DOS back to 3.0.

Sure it does not allocate something then ?
My Card has a ROM where it saves Configuration.
The Page Frame on my Card is still there even if Driver is not loaded.

I have had issues with VIDE-CDD on a rare few systems too. Even though it was originally developed by Oak Tech for Acer many think it is best but is not the fix all.
I found different older versions of Oakcrom.sys would work ok and generally use the OAK 91 driver from 1997 (41k) for those stubborn systems that dislike VIDE.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. https://archive.org/details/@horun

i forgot what it was called but there was a cdrom driver that did the contact tune through the floppy servo like this "bzzzt bzzzt bzzt buuzzt buuuzt ..... bzzzt bzzzt"
any one have it? i miss it!

Yes I'm sure, I've probed around in debug

I ultimately resolved the issue by switching IDE cards. Now the CDROM and EMS card are happily coexisting with VIDE-CDD loaded high and the page frame enabled
