Appendix A Configuration Options 15
MCMaster User’s Guide - Rev. B06 Kingston Technology Company
Interrupt Level
Default: Level 15
Options: Level 10
Level 12
This selects the hardware interrupt level that the MCMaster uses. There's no
reason to select a level other than 15, unless this conflicts with another adapter
already in the PS/2 system.
Option ROM Address
Default: D0000-D3FFF
Options: C8000-CBFFF
D8000-DBFFF
"Disable board"
The MCMaster has a n option ROM (Read Only Memory) that contains
program code to control the MCMaster's startup and operation. This entry
allows you to change the address to prevent conflicts with other adapters'
option ROMs. Note that the option ROM only takes up 16K (16384 bytes) of
option ROM space, even though its base address must be on a 32K boundary.
The "Disable board" option renders the MCMaster's ROM invisible to the
Micro Channel bus: don't select this option unless instructed to by Kingston
Technical Support for diagnostic purposes.
Model 80 ID (AIX)
Default: No
Option: Yes
The AIX operating system does a system check (INT 15h, Function C0h) at
boot time. In a Model 50 or 60, it will "think" that it is in an 80286-based
system, and not boot. Selecting "YES" causes the MCMaster to return the
system ID of a PS/2 Model 80.
