you can have the cdrom on the secondary controller.
Just tell the driver to check for the second controller, while some do this automagically others need to be told, as in the line in config.sys

DEVICE=VIDE-CD.SYS /P:170,15 /D:CDROM01

and the line in autoexec.bat

MSCDEX.EXE /D:CDROM01

for a litle more info https://www.vogonswiki.com/index.php/VIDE-CDD.SYS
and do realize that the lines shown are for reference and will only work if the files VIDE-CD.SYS and MSCDEX.EXE are in the root directory of the boot drive and or PATH directive.

Great thanks for the info I will give this a try!

Also, if VIDE-CDD can't find the drive on the secondary, try OAKCDROM

Many ISA IDE cards which purport to offer secondary channels do not properly generate IRQ 15

Some cards are called add-on ide and not specifically secondary. They may identify as 3th or 4th channel to avoid conflicts with any secondary ide channel that may already be present. Usually the known suspects like vide-cdd and oakcdrom pick them up with No problems but in some cases something refuses. One of my late 386sx boards had this problem and just refused to get the dedicated ide card working with a cdrom. The card works fine in another generic system. Eventually i added a soundcards with ATAPI support and that worked just fine.

Just to add some more information https://theretroweb.com/expansioncard/documen … ation/20327.pdf
The jumper settings for the Tyan S1342 VLB Multi IO controller.

It looks like there needs to be a jumper on J2 & J3 for both controllers to work... Though I don't see any clear indication of an enable/disable jumper.

I have found several cards which did properly respond on port 170h when jumpered for secondary, but still did not generate IRQ15.

I was under the impression that ATAPI cdrom drivers don't need a dedicated irq, just like what happens on quite some sound cards. But i can be wrong here.

Heartvent, can you tell us what happens if you put the cdrom drive onto:
- primary slave, instead of the CF
- secondary master without CF adapter attached
- secondary slave with the CF as secondary master

So I ended up with the hard drive on primary master; cf card on primary slave; and cd rom on secondary master. I had it hooked up this way before and didn't work but I must have had an issue with cables because it works just fine. The cd rom is detected by the driver ... I am using the philscomputerlab dos starter pack which uses the videcdd driver.

Jumpers are all defaults except J18 has pin 1& 2 closed to enable IDE-2. FYI, the jumpers for my version of the Tyan S1342 (1.6) is here..

Awesome that this is working ... thanks for the help and guidance!

VIDE-CDD requires a working IRQ

OAK I suspect does not

That would explain a little about the memory footprint I guess, as oak needs to figure out the alternative access?

Great to hear all is up and running! That vide-cdd really is an awesome driver because of its pretty small footprint.
