There used to be such a hack -- it's quite evil and fragile though. You
have to switch back into real mode to invoke the BIOS call, and you need
to preserve enough of the pre-boot environment that it can still work.
Running it in vm86 mode might also work, if you're lucky.
Seriously though, I wouldn't bother -- just implement a translation
layer in Linux which is compatible.
