[Coco] HDBDOS (IDE) & MESS (Coco2)

[Mark McDougall]

Hi all,

Apologies if this info is elsewhere but a search through the last few years 
of the mailing list archives didn't give me any hints...

I'm trying to run my HDBDOS (IDE) image with the Coco2 in MESS v152.

So what I've done is replace the disk11.rom image with my HDBDOS image; 
that's loading fine.

I then start up MESS with the -flop1 and -hard1 options specifying floppy 
and hard drive images respectively. The hard drive image I'm using is the 
one that works with my aforementioned HDBDOS image. I'm aware the RSDOS 
offset is not 'standard', but since my HDBDOS image matches my hard disk 
image, that should be OK - right?

I get the HDB-DOS startup screen, and then:

LBA HARD DRIVE NOT FOUND

This suggests to me that the issue is perhaps not with the image itself, but 
the emulation in MESS?!? What is HDBDOS doing to 'detect' an IDE drive? Is 
it issuing an IDETIFY_DEVICE command (I seem to recall that it is). I 
couldn't see any support for that in MESS's coco_vhd.c file... maybe this is 
the issue?

Regards,
