Most likely, there is a BIOS data area that is inaccessible to the BIOS code that gets invoked as a result of the interrupt, since most of the control stuff is implemented as BIOS traps, especially for the cheap-o processors, but also because you have to make the BIOS match the hardware implementation, and those vary widely. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
