Yeah, the disassemblies are not perfect. Interrupt handling is especially fuzzy (though F4C30 _should_ be somehow covered).

Had hopes (in the past) that an Intel (or IDA) expert steps in and improves it.

With IDA 5 Freeware you'd be able to improve the source AND follow the execution flow more easily (-> graph feature, jump back and forth etc.)

Unfortunately, i am away this week and can't provide the most up-to-date IDB file necessary.
