[Solved] Xircom - PCMCIA Ethernet - Thinkpad - OS/2 Warp 3 Connect

<< < (2/5) > >>

Steven Levine:
Many years ago I ran this card on a 770X.  I never could get the supposedly Card Services compliant CE2NDIS.OS2 driver to work so I used the point enabled XPSNDIS.OS2 driver.

I had other cards that worked with Card Services, so, unlike Richard, I ran with Card Services installed and setup Card Services to ignore the slot the Xircom was plugged into.

Here are my notes of the relevant CONFIG.SYS and PROTOCOL.INI entries

=== Overview ===

Using point-enabled in upper slot
Using IRQ 10

=== config.sys ===

REM Xircom uses IRQ 10
BASEDEV=RESERVE.SYS /IRQ:10 /MEM:D100,1000 /IO:320,20

REM Ignore upper slot - point enabled by Xircom
BASEDEV=IBM2SS14.SYS /IG0=1

REM -> Xircom PSCE2 9-11-97 v2.50
DEVICE=F:\IBMCOM\MACS\XPSNDIS.OS2

=== protocol.ini ===

[xpsos2_nif]

  DRIVERNAME = XIRCOM$
  IOADDRESS = 0x320
  INT = 10
  MEM = 0xD100
  NOEARLYRX
  VERBOSE

Marc, you are saying that you are using XIRCOM card CE2 but you have installed driver CE3NDIS.OS2.

Are you sure that is the correct driver for your card ? On the other hand, I cannot find anywhere a driver CE2NDIS.OS2.

Anyway, the driver that Steve has suggested (the point enabled driver) is here:

FYI: I found  a version here. (1994-10-05) and other here (1994-06-17)

Sorry for the late reply, had some hardware issues on the Thinkpad. The original drive died so I replaced with a flash card. The Xircom dongle also seems to be defective. I installed on a Windows 98 laptop and got the drivers installed but was getting inconsistent pings at the slightest touch of the dongle.

@Martin - I downloaded the drivers you posted, need to get a dongle to test. Thank you.

Question: Do I need to install IBM Peer for OS/2 or IBM LAN Requester 4.0 to access shares on my NAS?

This bring me back to where I'm at now:

1. OS/2 Warp 3 installed
2. PCMCIA Support NOT installed (thank you Richard)
3. Installed Xircom REM56G-100 card -> cem56_100 drivers - https://www.os2site.com/sw/drivers/laptop/cem56_100.zip
4. Configured card using Steven's settings
-Adapter memory address: D100
-Adapter IO address: 320
-Adapter IRQ: 10
-PC Card Slot: 2
-Emulate COM port 1 - 4: No
-Modem and Network share IRQ: Yes
-Enable verbose messages: Yes
5. Ping router address -> success
6. Ping www.os2world.com -> success

In case you want to retry your CE2 card with the driver set that Martin provided (say "FIN-XIR2.ZIP"):
the .NIF installation file would need a "brush up" to actually install the proper entries into the PROTOCOL.INI file.
Gleaning at the driver binary (CE2NDIS.OS2) and other .NIF files from Xircom, I think I would be able to provide you with a fixed .NIF file.

I can also see that even with the CE2NDIS.OS2 driver (and a corrected .NIF file), you will be able to ignore socket services and run the driver in "point enabled" mode which would allow you to always have PCMCIA support installed. If set up correctly via PROTOCOL.INI, the driver will just ignore/bypass the card services.

@Martin: would you see any issues in uploading these drivers to Hobbesarchive ? I am not the legal expert ...
