That’s one of the nice things about CPM3, all the actual hardware related stuff is localized.

Hi Thomas,
I got it working this afternoon - make sure you have the drive select code in all the places needed - has to be in the read and write routines as well as the hdlogin routine. You need to also update HDRVTBL.ASM to define the extra drive as well.

I have been working to get a 'no holes' dual drive CF system to boot in a non banked system for the last few days.
The system does not hang when it does not find the floppy controller, it gives the error you mention and then moves on.
Unfortunately if I enter the sector read section of HIDE3 and execute the drive select for the IDE card 0 or 1, my system then hangs.I am beginning to suspect the timing issues I originally encountered when testing the new board and selecting drives.
Even though I can execute the QO34,0 and 1 from the monitor and get the drive to select, there may still be issues when setting up and initializing things in HIDE3.
Dave, is your new code going to use much the same scheme to initialize, read and write sectors ?
Thanks,
