device64-0.1
-------------
---
With 'device64' it is very easy to examine block devices and tell wheter
they support 64bit commands or not.
---
NOTES:
[*]
Requires 68020(no FPU)+, OS2.04(theoretically)+, 4+ kilos of free memory.
[*]
Program does not output anything! The only indication is the '$RC' variable
which may be set to 0 - All OK, 5 - Device does not support 64bit commands,
10 - Error accessing device, 20 - Program failure(lack of args, bad OS ver,
etc).
---
HELP:
> device64 ?
PAR=DEV/A,U=UNIT/N,T=TD64/S,N=NSD64/S,A=AND/S
PAR=DEV/A - Partition or assign name or full device driver name. For
instance: DH2:, SYS:, scsi.device, ...
U=UNIT/N - Unit number when going to examine device directly. By
default unit 0 will be used.
T=TD64/S - Check if device supports TrackDisk64 commands.
N=NSD64/S - Check if device supports NewStyleDevice64 commands.
A=AND/S - This switch implies that when examining the device, both
commandsets must be supported. By default it is the OR so
if T=TD64 and N=NSD64 are specified and one of these is
found then the device is 64bit compliant.

USAGE:
; Check if device is accessible at all
failat 11
device64 scsi.device 1
if error
echo "No device was found on unit number 1!"
endif
; Check if SYS: partition is 64bit compliant
failat 11
device64 SYS: t n
if warn
echo "Your SYS: partition may be in danger!"
endif
; Check if 'FRAP' did patch the 'scsi.device'
failat 21
FRAP >NIL:
device64 scsi.device t n
if not warn
mount <partition>
endif
