Maybe off-topic: low/no cost Soft-ICE for x86

Hello, all:

    Another crazy project...

    While working on my old-DOS decompilation project, I've found that it
would be handy to have some sort of ICE hardware/software to watch the
boot-up sequence, examine specific registers, test code fragments, etc.,
without crashing my PeeCee. I've been using Debug and testing code fragments
to watch changes in the registers.

    Can anyone point me to a GNU/shareware software-based ICE program, much
like NuMega's Soft-ICE Windows, that can do this for DOS? Is it even
possible to use a software-based ICE in this instance (because it's before
DOS boots).

    How about this...how about a virtual PC running under OS/2 or Windows
NT? It would have to be re-bootable (without crashing the host operating
system) and support hot-key break-to-debugger. Sort of like a cross between
the vMac Macintosh emulator and WDEB386 (the Windows Kernel debugger). It
would be odd to emulate an 8088 on a Pentium 233MMX...hmmm...sounds like a
project.

    Any thoughts???
