I have a box that shares a swap paritition between FreeBSD and Linux, which can only be accomplisged via a DOS partition table. I would bet that the vast majority of laptops have FreeBSD plus a Microsoft OS installed on them, due to FreeBSD's inability to run some increasingly common laptop hardware. I also suspect that 95% of all FreeBSD machines with a DVD ROM drive in them are dual boot, laptop or not: DVD EOM drives are not better than CDROM drives, on FreeBSD. I know that _ALL_ machines with a BIOS requirement for DOS partitioning are running a DOS partition table. I also know that all machines with a BIOS requirement, due to antivirus requirements, which may be driven by the organization making the purchase, for an MBR that passes the 8 validity tests for an MBR, must be running something other than "dangerously dedicated", since FreeBSDs boot records and its boot manager do not pass these tests (e.g. the AA55 checksum to zero, etc.). For that matter, I guarantee all legacy machines with large drives are running an MBR that has a DOS partition table in it, with the MBR loading a BIOS patching TSR to add LBA support, and then adjusting the BIOS-visible location of sector 0. Also, if it's preferred, somehow, why do we call it "dangerously dedicated" instead of just calling it "default"? 8-p Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
