System hardware:
Compupro CPUZ, Compupro Ram17, Compupro System Support 1, Dual IDE CF card (A: and B:), ZFDC card with 5.25" drive C:
I built my dual IDE card earlier this year and have a very
reliable ‘no-holes’ system running from CF cards.
I have now finished the ZFDC board and can use it with either
3.5” or 5.25” floppy drives reliably with the ZFDCDIAG program.
When I boot CPM from the CF card it initializes the ZFDC board with no
errors.
I can not, however, access drive C: and D: from CPM
When I enter "A>C:" I see the following: ZFDC board display shows 'FF3B0' and Halt led comes on.
On the console it displays:
Floppy Disk drive Login Error (door open?)
ZFDC Board Sector Read Error
Bios Error on C: T-00001, S-00000
ZFDC Board Error Code =FFH
The Halt led clears and the ZFDC board returns to display FF000
I get the A> back on the console
Need some suggestions as to what I may be missing from my
code (system) - thanks in advance.
So, in my CPM3.sys file I have the following:
