Not numerous, just 8. That means that the trap is inside the kernel
rather than a 16-bit driver.

Not really. The documentation assumes you understand the terms. In that
case Theseus is useful.

First off what are you running? Warp4, eCS? Any FP's? Is there a
pattern to when the traps happen. What is the actual cs:eip value?
What's the ds and ss values? I should have had Peter include a sheet on
the rudiments of problem reporting in the Emergency folder. :-)

To have Theseus tell you something about where the trap occurs:

- System -> Kernel Information -> System Arena Table
- Scan down to the linear address with largest linear address
that is below your eip address
- LMB click on the address
- RMB -> Describe

If the owner is other than system, this might give you a hint as to the
cause.

If you had a trap dump image, you could know exactly what code failed not
that this will always tell you what to do the fix it.
