[comp.sys.amiga.programmer] Ralph Babel, What does gvpat.device check for before it opens?

drbit@phobos.UUCP (Jorgen Kjaersgaard) (06/01/91)

    I have a GVP A3001 rev 7 in my A2000 rev 6.5 with a Quantum 40AT
connected to it. When I try to prepare the harddisk, gvpprepat issues
the error message "can't open gvpat.device unit 0". I have even tried
to write an assembly program which attempts to open the device. DOS
loads the device all right but the device returns -1 on an OpenDevice
call. Gvpat.device is version 2.3.

    So, what does the device check in order to determine whether to
open or not? jumpers? something in the drive itself? boot EPROM (I don't
have a boot EPROM yet). Does my version of gvpat.device _require_ a boot
EPROM?

    Hope someone (Ralph Babel?) will help.
