Another trick is to use chmod and exer from the SRM if you wish to erase disks in order for FreeBSD to see them. Here is a typical command: chmod +w dka* exer -a w dka* & (It may error on the CD drive, depending on your config) That's it! Your disk(s) are now being "exercised" by the SRM. That actually starts with the first sector and wipes out the disk sectors by sector. It is an early version of DILX, for those of you familiar with Compaq storage. To check to see if exer is running, do a 'show_status' and see if exer has a PID, if so, then you can type 'init' and then proceed to install. One thing to note, if you want to kill a single drive instead of every disk that starts with dka like in the example, you will have to 'ls' and then find the "file" that the disk is associated with (ex. dkb0.2.0000.0) Then substitute dka* with the "filename" of your disk.

For future reference it's generally more helpful if you provide more information about a problem, such as a verbose boot output (assuming you are using a serial console and can cut'n'paste). If however your problem is that once you start sysinstall you get: da0: start 0, end 2050859, size 2050860 da0c: start 0, end 4294967295, size 0 da0: raw partition size != slice size da0: start 0, end 2050859, size 2050860 da0c: start 0, end 4294967295, size 0 da0: invalid primary partition table: no magic or something similar then: lqqqqqqqqqqqqqqqqqqqqqqqqqqqqq Message qqqqqqqqqqqqqqqqqqqqqqqqqqqqqk xNo disks found!

I tried doing this from the fixit prompt using the cd but it didn't work. If you still have a *nix os on the disk the boot it up and do: dd if=/dev/zero of=/dev/da0 bs=10240 count=10 (where da0 is the disk to do). If not, you will need to stick it in another system or find a friend with one. The install went fine after that for me. The machine has been fairy stable in the 3 months I've had it, although it has crashed a couple of times whilst running mysql under heavy load.
