CONFIGURING 900N/910N TO RUN OS/2, PCMCIA TOKEN-RING AND THE NOVELL 
NETWARE REQUESTER 


PROBLEM

When configuring an Ascentia 900N/910N notebook to run OS/2 (2.11 or Warp), 
PCMCIA Token-Ring, and the Novell Netware Requester, the system does not 
recognize the Token-Ring adapter and shows there are no resources available 
to that adapter, when viewing card status in the PCMCIA configuration.  


CAUSE

There are differences between the way OS/2 v2.11 and Warp map resources with 
regards to PCMCIA support.   Warp utilizes a resource manager that queries 
the system memory and finds ROM BIOS from C0000-CBFFF.  
Even though the system is queried, Warp still attempts to map available 
space in an illegal area.  

OS/2 2.11 does not have a resource manager and is unable to detect the ROM 
BIOS.  OS/2 2.11 has an RMU (resource map utility) that excludes certain known 
resources from being used by card services.  The AST2RMU1.SYS file used by 
OS/2 2.11 was initially designed by IBM for the PowerExec and does not 
correctly identify and exclude the C0000-CBFFF range.  The Token-Ring driver 
by default uses CC000 and D8000 for memory mapped IO and shared RAM.  To make 
the adapter work, you must make additions to the NET.CFG file.

SOLUTION

Below are the steps required to install OS/2 2.11 or Warp, PCMCIA Token-Ring 
and the Novell Netware Requester in your notebook computer.

1. Install OS/2 by following standard procedures as specified in the 
documentation provided by IBM.

2. Install and configure the proper SSVLSI driver that is specifically 
designed for AST portable systems, which utilize the VLSI PCMCIA chipset.  
The file name for OS/2 v2.11 is OS2P21.ZIP; and for Warp it is OS2P30.ZIP.  
Follow the directions contained in the README file included with each zip file.  
These files can be located on the IBM BBS at (919) 517-0001.  
Follow this path:

3. Install the OS/2 Novell Netware Requester v2.11 and use the TOKENCS.SYS 
driver.  This driver is not on the list of choices available so you must type 
it in manually.  (When entering the driver name, type exactly as listed above).  
Install the Token-Ring driver disk v3.01 which is created from the 
TRCCA301.ZIP file.  Follow the directions contained in the README file 
included with the zip file.  This file can be found on IBM's OEM BBS 
(919) 543-6004.  Follow this path:

Type file name

4. Make the following additions/changes to the CONFIG.SYS (OS/2 2.11) 
and NET.CFG (OS/2 2.11 and Warp) files.

Additions:

WARP:  Make the following additions to the NET.CFG file.

   PCMCIA
   MEM #1 D4000
   MEM #2 D8000

OS/2 2.11:  Make additions to both the CONFIG.SYS and the NET.CFG files.

CONFIG.SYS ( in PCMCIA section)

Change: 
	BASEDEV=AST2RMU1.SYS
To:  
    BASEDEV=AST2RMU1.SYS /MX=C0000-CBFF

NET.CFG

   PCMCIA
   MEM #1 D4000
   MEM #2 D8000
