Hi all,

I have a simple query here related to the working of ProDOS 8 kernel on a
slotted Apple 2 and the interface to slot ROM based device drivers.
I am currently using ProDOS 2.4.1 with an old version of ProDOS BI (i.e. BI
1.1).
The Prefix being set to a location in an online volume supported by a device
which ProDOS device driver reside on a slot ROM (entry point $C75F for my
Omnidisc SCSI device in the Virtual 2 emulator (likely to follow the
Smartport protocol itself).
At BI prompt, issue the keyboard sequence below:
]CALL-151
*C007:0
]CAT
=====> Screen cleared + test routine run and the mention IOU appears. The
test routines for the enhanced Apple //e see to be located in âge $C6 and
$C7 of the internal CX ROM.
My query is that, wouldn't it be better to set the SLTCXROM ($C006) from
within ProDOS before calling such device drivers?
Forgive me if this has already been discussed in this newsgroup.
Thank you for any feedback on this point,
Best regards,
Benoît
