[Coco] Discrepancy between HDBLBA.ROM and the /I0, /I1, /IH device Descriptors

[Kip Koon]

Hi Retro Canada!
Good Question.  Yes the jumper is strapped to 50 for the $FF50 rom and 70
for the $FF70 rom.  Each time I changed the eprom, I also changed the jumper
on the Glenside IDE Controller.  Still does not see the CF Card in the "50"
mode. Thanks for asking.

what about the jumper on your card? it must match the rom and descriptors
address. this is not a soft but a hard setting

Hi NitrOS-9 Experts!

Here is my problem.  I have HDBLBA.ROM running on my Glenside IDE Controller
at the address $FF70.  The /I0, /I1 and /IH device descriptors have
HPA=FF50.  I have patched the rom image at $D93C from $70 to $50 to match
the descriptors, but the rom never sees my CF Card.  I've also tried
changing HPA to $70 in /I0 and /I1 with the Glenside IDE Controller at $FF70
to see if NitrOS-9 would see my CF Card.  In other words, I've tried the rom
and /I0 and /I1 at $FF50 together and at $FF70 together.  The Glenside IDE
Controller only works at $FF70 in the ROM and NItrOS-9 does not work at
either $FF50 nor $FF70.  Is there something I'm missing?  What else should I
check?  Thanks in advance you guys.  Take care my friends.
