>Description:
After configuring and building kernel on initial installation, re-boot 
appears to be satisfactory until:
message 'changing to device wd1a' appears, then 'panic: can't mount root'
followed by a 15 second interruptible delay before an automatic reboot.
FreeBSD is being installed from a '/bin'-only DOS directory onto a second
EIDE disk; 'C' drive is DOS-only (Win95) with boot-manager, disk2 is 
dedicated to FreeBSD with a 'compatible' DOS partition, default FreeBSD
partitions and sizes. Disk2 is hardware-fault free and is 1.2 Gb. Kernel
config appears to be ok.
>How-To-Repeat:
Easily repeatable: won't go away! Various combinations of dedicated/almost
dedicated (DOS) partitions, boot manager/non-boot manager tried. 'Novice'
installation being attempted with 'custom' option - just /bin specified.
Is the /bin directory the ONLY one required for a minimal installation?
