Windows 9x has a variable timer rate.

• 18hz at boot
• 1000hz at login screen
• 200hz at desktop
• 18hz at shutdown

TSKIP of 86 might be sufficient to provide the same level of updates as on DOS (which uses 18hz) for the 200hz case. The documentation doesn't say how fast we can send updates to the watchdog. At 1000hz with a TSKIP of 86, the watchdog would be updated 10 times a second rather than twice. Another problem is at shutdown, if we are updating based on a 200 or 1000hz timer, when the system returns to 18hz the watchdog will reboot the system unless the timeout is set really high.

Adjacent memory block being corrupted, was present prior to lockfile handling

Might be nice to have, rather than opening a DOS prompt or exiting Windows to change watchdog settings.

I am willing to write support for other boards I currently do not own, but I will need a PDF manual indicating how the watchdog works on that particular board since they all seem to be different.

Possible candidates for future 486 CPU boards:

• PCA-6149 (2 ports, reads only, timer only adjustable by jumper)
• PCA-6148 (2 ports, write port enables, read port disables)

The 6149 supports pentium overdrive, which may be desirable.

286/386 CPU boards do exist, but unsure if there are any with socketable CPUs.

don't run if there is an existing instance, may need to use a lock file to accomplish this
