[Coco] The ultimate VCC hard disk image using EmuDsk

[Bill Pierce]

Barry, where are you putting the VHD? If you are putting it in "HD Drive 0", then you are not even using the SuperIDE. The SuperIDE'dll uses the "IDE Master" & "IDE Slave" slots, which will not (by default) even accept a VHD image, only "xxx.img" files. Not sure, but I think CF cards use FAT16 or FAT32 (I could be wrong, they may use just files like VHDs) where VHD files are just a 'file'.|
If you are putting it in "HD Drive 0", then EmuDsk is using it in NitrOS9, not SuperIDE. You're not going to access those drives in NitrOS9 without rbsuper, llide, i0, and i1 installed.
And hdblda will not access the "HD Drive 0" slot from RSDOS, it is looking for "xxxx.img" to be in "IDE Master".

I am able to access vhd images just fine from NitrOS9, but HDBDOS does not see a
drive mounted using any rom I tried. What would be the difference, anyway,
between an image from a CF card, an image from a hard disk, or any other image?
Wouldn't they all be just a bunch of sectors? Anyway, why would NitrOS9 work but
HDBDOS not see the disk?

right rom, but that emulation is meant for using CF card images (copied from CF
cards) in the Master and Slave slots, not VHDs.

standard "rbsuper.dr" and "llide.dr" for drivers. The descriptors, "/i0" & /i1"
must be set properly for accessing the SuperIDE.dll. I can't remember those
settings at the moment, but I could find them on one of my old VHDs setup for
that configuration if needed.

used the SuperIDE.dll quite a bit and it works, but you need a method of making
CF card images.
