I've been having a tough time installing 2.0R on an Olivetti 486 machine with 16Mb RAM and a Quantum 122Mb IDE drive. AMI bios if that's relevant. The problem seems to be the MBR that fdisk lays down. I can install DOS no problem, it boots fine, but if I install FreeBSD (using the whole disk) the machine won't boot. The BIOS boot messages come up OK (memory test, config stuff) then as soon as the machine goes to the hard disk it says "Read Error". The way I worked round it was to put down a 1Mb DOS partition (after fdisk/mbr of course) then install FreeBSD on the rest of the disk. Then I boot DOS and fdisk/mbr to write a valid MBR, then use DOS fdisk to mark the non-DOS partition active. I think I can use a combination of DOS fdisk/mbr and FreeBSD fdisk to create a FreeBSD only hard disk, but I'll need a shell to do it from - the graphical sysinstall is pretty but it doesn't seem to let you run fdisk with arbitrary parameters :-( Aled -- aledm@relay-europe.ps.net | tel +44 973 207987 Perot Systems Europe Ltd. | fax +44 181 476 2419
