Here is a list of hp300 specific kernel compilation options and what they
mean:
-HAVEVAC
- Compiles in support for virtually addressed cache (VAC) found on
- hp320 and 350 machines. Should only be defined when HP320 and/or
- HP350 is.
-
HP320
Support for old hp320 machines: 16mhz 68020, HP MMU, 16mhz 68881
and VAC. Compiles in support for a VAC, HP MMU, and the 98620A
- 16-bit DMA channel. Forces the definition of HAVEVAC.
+ 16-bit DMA channel.
HP350
Support for old hp350 machines: 25mhz 68020, HP MMU, 20mhz 68881
and VAC. Compiles in support for a VAC and the HP MMU. Differs
from HP320 in that it has no support for 16-bit DMA controller.
- Forces the definition of HAVEVAC.
HP330
Support for old hp330 (and 318/319) machines: 16mhz 68020, 68551 PMMU

designated way. Somewhat frivolous, but the heartbeat LED is
useful to see if your machine is alive.
-PANICBUTTON
- Compiles in code which will enable a "force-crash" HIL keyboard
- sequence. When the Reset key is typed twice in succession (within
- half a second) the kernel will panic. Note that the HIL Reset key
- sends a NMI to the processor which will get the CPUs attention no
- matter what it is doing (i.e. as long as it isn't halted). Alas,
- also note that the NMI is only sent when the keyboard is in "cooked"
- (ITE) mode. If it is in "raw" mode (i.e. X-server is running) the
- Reset key is just another keypress event. A cheezy substitute in
- this case is holding down the upper right-most unlabeled key and
- then pressing the unlabeled key to its left. Note that this only
- works if HIL (level 1) interrupts are not masked.
-
DEBUG
Compiles in a variety of consistency checks and debug printfs
throughout the hp300 MD code and device drivers.
