Adaptec OS/2 driver

Your Adaptec adapter's OS/2 driver supports OS/2 version 1.3 through OS/2 version 4.0 (also known as OS/2 Warp). We do recommend that you use or upgrade to the latest version of OS/2, IBM's OS/2 Warp Connect. IBM's OS/2 Warp Connect contains OS/2 Warp, plus all available protocol stacks and network clients for use with OS/2. If you choose to run an older version of OS/2, you may need to obtain your protocol or client files from third-party sources. Your Adaptec OS/2 driver supports connections to all of the following network operating systems:

  • Novell NetWare
  • OS/2 Peer client
  • IBM LAN Server
  • Windows NT
  • Windows 95

Follow the instructions below to install the Adaptec OS/2 driver using OS/2 Warp Connect. If you are using an older version of OS/2, refer to the installation documentation that came with your OS/2 software.

Pre-existing OS/2 Warp Connect Installation

Use the following instructions if you already have OS/2 Warp Connect installed on your machine. (If you are installing OS/2 Warp Connect for the first time, go to the "New OS/2 Warp Connect Installation" section below.

  1. Double-click the MPTS (Multi-Protocol Transport Services) icon on your desktop.
  2. Select "Install."
  3. Select "Install Additional Network Drivers," and specify "a:\ndis.os2" as the source. Select "OK."
  4. After the OS/2 driver is copied from the diskette, select "OK."
  5. Select "Configure."
  6. Select "LAN Adapters and Protocols" and then click "Configure."
  7. In the LAPS dialog box, under Network Adapters, highlight the Adaptec adapter and click "Add." Under Protocols, highlight the desired network protocol(s) and click "Add."
  8. You can modify adapter or protocol settings under Current Configuration. To change any settings on the Adaptec adapter, highlight the adapter and click "Edit."

  9. Optional configuration parameters are described below.

    SPECIAL NOTE: If you selected "IBM NetWare Requester Support" from the Protocols box, you will need to make the following configuration changes: Highlight "IBM NetWare Requester" in the Current Configuration box and select "Edit." Change the "Token-Ring Support Option" to NO. Next, enable one more of the listed Ethernet frame types by specifying YES in the appropriate boxes. (If you are not sure which frame type(s) are used on your Novell NetWare network, enable all of them). Finally, change the "Network Adapter Address" to the Ethernet address of your Adaptec adapter. You can run A:\EMDIAG.EXE from your Adaptec diskette at an OS/2 command line prompt, and choose "Configuration Status," to display your adapter's Ethernet address.

  10. After making any desired configuration changes, click "OK."
  11. Select "Close" from the Configure dialog box.
  12. Select "Exit" from the Multi-Protocol Transport Services dialog box.
  13. Next, choose "Update CONFIG.SYS" and then select "Exit."
  14. Shutdown OS/2 and reboot for your network driver and protocol(s) to take effect.

New OS/2 Warp Connect Installation

Follow these instructions if you are installing OS/2 Warp Connect for the first time.

  1. Follow the general installation instructions provided with OS/2 Warp Connect to begin your installation.
  2. During the installation, you will specify the type(s) of networks you are using.
  3. After choosing your network type(s), the OS/2 installation program will ask you to specify the type of network adapter you are using. Choose "Other Adapter," and specify "a:\ndis.os2" as the source for the Network Adapter Driver Disk. Select "OK."
  4. OS/2 will confirm your choice by displaying a "Drivers Found" message.
  5. Specify "Ethernet" as the type of LAN and choose "OK."
  6. Choose "OK" twice more to confirm your choice.
  7. Continue through the rest of the OS/2 installation, following the on-screen instructions.

Driver Parameters

DRIVERname="value"

Identifies the adapter's driver name. Each adapter installed must have a different driver name.

Default: EMPCI$
Range: EMPCI$, EMPCI2$, EMPCI3$, etc.

MAXRECEIVES="value"

Specifies the number of receive buffers that the network driver will allocate. Memory use is approximately 1600 bytes per unit.

Default: 8
Range: 1-8

MAXTRANSMITS="value"

Specifies the number of simultaneous transmit requests that the network driver may queue. Memory use is approximately 150 bytes per unit.

Default: 8
Range: 1-8

NETADDRESS="value"

Overrides the network address of the network adapter board. This parameter should only be used if there are duplicate addresses on the network. If this entry is specified, its value must be a valid individual address(i.e. not a broadcast address). The value of this parameter is a string of 12 hexadecimal digits enclosed in quotes, for example:

NETADDRESS="00BAD0BEEF00"

Full Duplex = "true" or "false"

This adapter forces an adapter using twisted pair calbing to operate in full duplex mode. Full duplex can greatly increase network throughput because both transmit and receive pairs can be active simultaneously.

The default mode is half duplex, where only one pair is active at a time.

Default: FALSE
Range: TRUE | FALSE

Transceiver = "AUTOSENSE","INITSENSE","ACTIVESENSE", "UTP", "THICK", "THIN", "TX","T4"

This parameter selects for the cable type in use.

Default: AUTOSENSE
Range: AUTOSENSE | INITSENSE | ACTIVESENSE | UTP | THICK | THIN | TX | T4

These parameters can be used to specify how you would like to configure the adapter with regards to connection type.

ACTIVESENSE="TRUE" or "FALSE"

This parameter configures runtime autosensing. Runtime autosensing allows the adapter to adjust to a change in cable type or line speed without requiring a driver reload. (When configured for ACTIVESENSE, the driver will also display a message if a cable break occurs.) Do not use this parameter if no cable is attached to the adapter or Quartet port.

Default: FALSE
Range: TRUE | FALSE

SharedIRQ="true" or "false"

This parameter is for OS/2 only and enables or disables shared interrupts.

Default: TRUE
Range: TRUE | FALSE

By default, the EMPCI.SYS or EMPCI.DOS driver will find the first uninitialized Adaptec Ethernet port in the system. Initialization of multiple ports will therefore proceed sequentially. You can, however, use PCIBUS and PCIDEVICE parameters to discretely specifying individual Ethernet ports.

PCIBus="value"

This parameter determines the PCI Bus of the Ethernet port you wish to initialize. This value can be determined by first running the EMSETUP diagnostics program.

Default: 0
Range: 0 - 255

PCIDevice="value"

This parameter determines the PCI Device ID of the Ethernet port (on a specific bus, determined above) you wish to initialize. This value can be determined by first running the EMSETUP diagnostics program and looking at the value reported under "Configuration Status".

Range: 0 - 32
example: [EMPCI_NIF]
DRIVERname=EMPCI$
PCIBUS=1
PCIDEVICE=4

This references the device #4 on bus #1. for a Quartet, this would be the first port.
