6200/6300 BIOS Interfaces
These are the standard PC BIOS interfaces that support the 6200 and 6300
Computers.
Interrupts Supported by the BIOS
The 4000 Series interrupts that are supported by the 6000 Series BIOS are
matrixed into the entire set of interrupts.
The interrupts, with their symbolic notations, are listed in the
Interrupt
Definitions
paragraph, starting on page 6Ć30. See the
Interrupt Index
(in the
Index
section, at the end of this publication) to locate interrupts alphabetically.
The 6200/6300 BIOS supports (hooks) interrupts that are listed in the table
below. But, keep in mind that applications that support any of these interrupts,
handle those interrupts it supports, provided the application has not been
configured (by the use of switches) to
ignore
specific interrupts.
The following interrupts are supported by the BIOS:
