It is my low level x86 debugger. Under 386BSD and FreeBSD I used it to debug the boot blocks, kernel startup and general kernel things before ddb was ported to 386BSD. ddb is better for general kernel things except it is sloppy about disabling interrupts so interrupt handlers can be hard to debug. I haven't used my debugger in the kernel for a year or two :-). Bruce
