The big problem that I hit with some experimental code was that I tried to force an interrupt and if I guessed wrong that interrupt could hang the whole machine. Ooops. I'll have to try again. : However, that code had problems in that it didn't work if FreeBSD had no : driver for a particular piece of hardware, and assumed the IRQ was free : even if it wasn't. Although, from hearing Mike Smith talk, the new VM86 : and PnP code should have 'informed the kernel' of all such resources : used, even if FreeBSD had no driver for the hardware. The newer pnp code will help a *LOT*. There are some issues still, but it is much better than before.
