Installing and Configuring Enhanced OS-9

Enhanced OS-9 for X86 PCAT 67

How to modify the OS-9 descriptor

Edit the file

MWOS/OS9000/80386/PORTS/PCAT/SPF/SP8390/DEFS/spf_desc.h

and change the following fields as required:

#define PORTADDR0x00000300/* Base address of hardware */

#define VECTOR0x4a/* Port vector */

#define CPU_BASE0xcc000/* CPU BASE */

#define RAM_SIZE0x4000/* RAM Size */

Then remake the descriptor: change to the

MWOS/OS9000/80386/PORTS/PCAT/SPF/SP8390 directory and type:

os9make -f=spfdesc.mak

You have now created a new descriptor. Next time you run the Wizard,

it will use the new descriptor.

3COM PCMCIA

3COM EtherLink III PC CARD

3COM Megahertz LAN (3CCE589ET) - 10 Mbps LAN PC Card

System State Debugging - Supported

Default Settings

PORTADDR 0x340 /* IO port for ISA */

IRQVECTOR 0x43 /* IRQ vector */

CONNTYPE INF_EXT /* Auto */

Solving Configuration Issues

Connection Type

The default connection type is set to INF_EXT (auto). For the 3COM

PCMCIA card this implies the card will detect the connection type used.

If desired the connection type may be forced. To force the connection

type the descriptor must be changed.

Interrupt Conflict

Another problem may be the interrupt used. The default interrupt is

IRQ3. In this case you have the following options.
