Hi Garth,
GR> I've been pulling my hair out over this one...
GR>bought a new internal 28.8 PNP (has paper insert in docs says its
GR>a 33.6) 
GR> I run OS2 and my drives are all HPFS
GR> motherboard is an Intel " PLATO " with the
GR> latest bios update and a P90 cpu with a
GR> Cirrus logic PCI video card
GR> I can't find the modem at all...
GR> all my diagnostics say the mouse is the
GR> only com port in the system. I even went as far as
GR> turning off the other comports in the bios and
GR> pulling all the cards except my video card and modem.
GR> the legacy install program doesn't seem to 
GR> work properly it hangs half the time right at the end
GR> before it sets up the modem... (guess it can't find it)
GR> I've reinstalled my Supra 14.4 internal and it works fine
GR> (this one has jumpers hint hint... )
GR>  This Plug and Pray crap is making me crazy...
GR> I even went as far as taking one of my drives, formatting it 
GR> as a FAT drive and then disconnecting my other drives and booting
GR> of the FAT one...
GR>  It still didn't work...
GR>  Is there a problem with the Intel PLATO motherboard and chipset???
Not necessarily.  However, if the bios is not "plug and play" the 
process is not easy:
INSTALLING THE SUPRA PNP MODEM WITH OS/2 WARP
Supra Plug and Play modems are intended for use on MSDOS based systems 
(version 5.x or greater) running either Windows 3.1/3.11 or Win95.  
However, we have been able to test and use our modems on OS/2 systems.
The following instructions are for a Legacy installation using the Plug 
and Play Utility disk and the WinICU Diagnostic disk. Both are necessary 
on a machine that doesn't have a Plug and Play BIOS. 
1) Boot the computer to MS-DOS. If the system is setup for Dual-Boot, 
then double-click on the Dual-Boot icon in the Command Prompts folder, 
or in any OS/2 or DOS session type in the following command:
        C:\OS2\BOOT /DOS
If you are running OS/2 with the Boot Manager, then boot to the DOS 
partition.
2) Insert the Plug and Play Utility disk in the floppy drive and change 
to that drive letter. Type in "INSTALL" (minus the quotes) and press 
enter. Accept the default directory of \SUPRA and install for DOS only.
3) If your system is setup with a Dual-Boot setup, then you can allow 
the install program to modify the CONFIG.SYS and add the PnP device 
driver. If you are on a Boot Manager setup, then say no. After the 
installation has completed, make sure first line of the OS/2 config.sys 
is device=c:\supra\dwcfgmg.sys".
4) Copy the ESCD.RF file to the root directory of the OS/2 boot 
partition.
5) Either Dual-Boot (C:\OS2\BOOT\ /OS2) to OS/2 or reboot the computer 
and boot the OS/2 partition.
6) When OS/2 has loaded and you are at the Workplace Shell, then open a 
DOS windows or Full Screen Session. At this time the Plug and Play for 
MS-DOS driver will load. Change to the drive that contains the \SUPRA 
directory, and type in WTM. Record the I/O address and interrupt 
request. If the modem has been configured for a COM port or IRQ that is 
already in use in the system, then you can install and run the ICU 
program to change the resources for the modem. ICU can be installed in a 
DOS session under OS/2 without having to boot to DOS. Also install for 
DOS only with this program.
7) After you have the I/O address and interrupt request you can modify 
the parameters for the OS/2 COM driver in the CONFIG.SYS file. Look for 
DEVICE=C:\OS2\COM.SYS and add modify the line to add the modem 
parameters:
        C:\OS2\COM.SYS (COM3, 3E8, IRQ10)
In this example, the modem was configured for COM 3, 03E8, IRQ 10. Be 
sure not to include the leading 0 for the I/O address. It is not 
necessary. Use the same command line parameters for SIO drivers as well. 
Save the file. You will need to reboot before you can access the modem.
A Note on COM drivers:  The OS/2 COM.SYS file is not very effective and 
many OS/2 users suggest that you obtain Ray Gwynn's SIO COM drivers as a 
replacement. The same command parameters for the COM driver apply.
A Note about IRQs: OS/2 is very particular about what IRQs can be used 
in the system. It expects certain devices to use specific IRQs.  IRQ 5 
most often used for a soundcard. IRQ 7 is the parallel port. If you 
decide that you need to use these IRQs, then be prepared for possible 
problems. In the test case, the modem was configured for IRQ 11 with no 
problems.
With the above configuration, the modem should be able to work in all 
areas of OS/2 (i.e. DOS session, Win-OS2 session, OS/2 session, and the 
Workplace Shell).
Thanks,
