Sorry for bringing this old post back again. I, too, trying to remove F1 prompt but I'm using GMirror and wanted to ask what's gonna be the device for me? This is what I have:
[2.4.3-RELEASE][admin@pfs17]/root: df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/mirror/pfSenseMirrors1a 129G 960M 118G 1% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/md0 3.4M 164K 3.0M 5% /var/run
devfs 1.0K 1.0K 0B 100% /var/dhcpd/dev
procfs 4.0K 4.0K 0B 100% /proc
fdisk -B pfSenseMirror doesn't look very right to me. There are two underlaying SSD drives working as ada0 and ada2 - how do I do it?
