Hello again, I did a some googling and I found this source forge project which strives to emulate a DPMI style interface for linux/bsd. Here's a link: http://sourceforge.net/projects/lrmi/ Anyone know if this thing works? I'm going to try it and find out. Thanks, -Jason -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Jason Dictos Sent: Tuesday, March 09, 2004 2:04 PM To: 'freebsd-questions@freebsd.org' Subject: Using int 13 while BSD is running Hello, I'm investigating what resources are out there for accessing bios addressable devices while BSD is up and running. The situation is this, currently we licenses Caldera DOS for a program we wrote which uses the int13 extensions to manipulate the systems hard drive (i.e. to recover partition tables and what not). This forces our application to be written in 16 bit mode, but it does allows us to not have to worry about loading any driver which would be hardware specific to access the hard drive. Is there any way to write a driver for BSD which would put the processor into real mode, therefore allowing us to use the int 13 api of the bios to read and write hard drives? That way we could package a stripped down BSD kernel which loaded our driver and gave our application access to hard disks without having to load any device driver. Apologies in advance if this is the wrong mailing list, -Jason ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
