The Sinclair QL Forum

Have you ever tried to use both QL-SD and vDrive devices in parallel?

In my case after QL-SD driver is loaded I cannot reach the vDrive because for all calls to "mdv*_" the response is delivered by the QL-SD. Can I change this behavior?

Tested with EN Minerva 1.98, Miracle memory card, QL-SD card driver v0.07.078.

This is the old buggy Qubide based driver. I suggest to update to the new version.

But beware, the new driver uses a different image format (QXL.WIN, like all emulators)

Do you mean this driver "QL-SD card driver v0.07.078"?

If so, how can I update it? I've looked for some resources without success...

Yes, unfortunately this can only be updated using an (E)EPROM programmer. I provide the images here https://www.kilgus.net/ql/ql-sd

If you want to stick with the old driver, look if you have SDC_USE "MDV" somewhere in your Bootfile and remove it.
Or try SDC_USE "WIN".

I tried to use SDC_USE "WIN". It causes QL-SD not to respond to "MDV" but the vDrive cannot be reached (in a normal way by using "MDV3_").

This is strange, since normal microdrives work. Did you check your bootfile? Does your normal microdrive respond?

Does vDrive work if you abort the QL-SD ROM initialisation sequence by a key press?

Hm, I'm new to QL, so if you ask "check your bootfile" I have no clue how to do this .

The QL starts as expected. If I abort the QL-SD initialization sequence nothing changes. MDV1 responds as expected. I have also a second QL without QL-SD where vDrive works without any problems.

Well, when MDV 1/2 works then I don’t think your problem is related to QL-SD.
