*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:
