> I have two of the Glenside IDE interfaces, with all the disks and documentation, and have modified one to have two edge card adapters in Conn2 and Conn3. I have a handful of IDE drives as well.
> After creating a new boot disk using various methods, including the OS-9 config command and ezgen modifying a system disk backup, I am still unable to boot up OS-9 with a /h0 device.
> I've read through the documentation provided numerous times and am able to use the IDE_Detect program provided to detect the drive that is attached, but the OS-9 Boot always fails.
> I've tried it with the card inserted into the number 3 slot of an MPI and the floppy in the number 4 slot (only time the led gives any indication of activity from the drive). I've tried it with the floppy controller attached to CONN2 of the interface card. Nothing seems to work.
> I've been using the $FF50 driver mostly, but when the interface card was directly put into the COCO3 I have tried it with the $FF70 driver.
> I must be missing something here. Has there been any updates to the drivers or documentation since they were first released? I packed up the CoCo3 stuff shortly after getting them from Glenside and I may have missed something.
How big is your bootfile (OS9Boot)??
There is an upper size limit of about $8200 (33280) for the bootfile.
I've hit it many times building Hard Drive bootfiles.
