Making the descriptors

Once the systype.h file has been updated the new descriptors may be

created.

Change to directory:

MWOS/OS9000/80386/PORTS/PCAT/SCF/SC16550/DESC

Type os9make; the following descriptors will be made:

MWOS\OS9000\80386\PORTS\PCAT\CMDS\BOOTOBJS\DESC\SC16550\term1

MWOS\OS9000\80386\PORTS\PCAT\CMDS\BOOTOBJS\DESC\SC16550\t1

Digiboard

Support for the Digiboard intelligent serial card is included by selecting

the Digiboard option in the Configuration Wizard’s Bootfile Options

dialog box.

To change the vector the user must edit the systype.h file located in the

port directory.

MWOS/OS9000/80386/PORTS/PCAT/systype.h

#define DIGIPORT 0xe0 /* port address of DIGI board status reg. */

#define DIGILEVEL 0x45 /* 16450 keyboard controller */

#define DIGIVECTOR DIGILEVEL /* irq vector same as irq level */

#define T10PORT 0x320 /* t10 onboard port address */
