In SJIICX.TXT, Jerry Crofoot reports that "the ScanJet IICX works
great under OS/2 Warp and DeskScan Version 2.1".  He details a
procedure for installation that requires "the HPC2502/3A
SCSI controller board that came with the scanner . . . the new
Switchless board".  He suggests that "none of these steps can be
missed."  But Warp can also operate the IIcx and DeskScan v2.1a
with third-party SCSI adaptors; and there are several ways to
install and run DeskScan (and scanners generally) under both Warp
(OS/2 v3.0) and OS/2 v2.x.  I use an Adaptec 2742T.  With this
adaptor, DeskScan works well under MS Windows v3.1, and under
Win-OS/2 derived from OS/2 v2.11 CSD Fullpack (syslevel XR06200)
which I ported to Warp (XR03000) using WINSTALL.CMD
(in WINSTALL.ZIP).

Although the procedure below deals specifically with Warp, the
same file *names* are required by OS/2 v2.x.  Unlike Warp, the
scanner files required by OS/2 v2.x are NOT all embedded in the
operating system, but are available (in early, serviceable
beta versions) in file VASPBETA.ZIP on the OS/2 Shareware
BBS or (as VASPBETA.EXE) on the Adaptec BBS (408-945-7727).

.................................................................

One driver supplied by IBM and embedded in Warp must be specified
in CONFIG.SYS:

BASEDEV=OS2SCSI.DMD

Two drivers supplied by Adaptec and embedded in Warp must be
present in your \OS2\BOOT directory (the \OS2 directory in v2.x)
and specified in CONFIG.SYS:

BASEDEV=AIC7770.ADD /V   <<< specific to Adaptec's 274x
                             adaptor family
                             N.B.:  *Different .ADD files* will
                             be required by different adaptors!
BASEDEV=OS2ASPI.DMD      <<< ASPI for OS/2

One driver supplied by Adaptec and embedded in Warp must be
present on disk and specified with fully qualified path in
CONFIG.SYS:

DEVICE=d:\OS2\MDOS\VASPI.SYS <<< ASPI for VDMs, i.e. for
                                 OS/2 "Virtual DOS Machines"

Additionally, WINASPI.DLL and VASPID.386 (both supplied by
Adaptec and embedded in Warp) must be located in the \SYSTEM
subdirectory of your Windows installation(s), e.g.
d:\WINDOWS\SYSTEM or d:\OS2\MDOS\WINOS2\SYSTEM.

Comment out any reference to MINI400I.SYS or WIN400I.386 in
Windows file SYSTEM.INI located in the main Windows subdirectory,
e.g. d:\WINDOWS or d:\OS2\MDOS\WINOS2 (place a semi-colon ";" at
the beginning of any line(s) that refer to those two files).

Open the Settings Notebook for the Windows object, located on the
OS/2 Desktop.  Open the "Session" tab and click on "WIN-OS/2
settings".  Select "All DOS and WIN-OS/2 settings", and then
"DOS_DEVICE".  Enter "d:\path\SJIIX.SYS" in the Device
window that opens up, and click on "Save".

Reboot.  Good luck.
