FreeBSD single user?

Thanks for your response...
I tried to press Enter and then Cntl + D and that didn't help either. Sorry for the delay, it took a while to type all of this from the screen.
Here are my scenarios:
Scenario 1:
----------------
After I power cycle the array, it boots up and comes to this:
F1 FreeBSD
F2 FreeBSD
F3 FreeBSD
F5 Drive 1
Default: F5
I hit Enter and it changes to this:
F1 FreeBSD
F2 FreeBSD
F3 FreeBSD
F5 Drive 2
Default: F1
I hit Enter and space (I think), it drops me down to this:
>> FreeBSD/i386 BOOT
Default: 1:ad(1,a)/boot/loader
boot:
At the boot: I type /kernel -s
It goes through the boot process and these are the lines before I hit my road block:
"Enter full pathname of shell or RETURN for /bin/sh:"
the lines are:
Mounting root from ufs:ad1s1a
Root Mount Failed: 6
Mounting root from ufs:ad1a
Root Mount Failed: 6
Manual root file system
gives me an example
then it drops me down to this prompt:
mount root>
I type:
mount root> ufs:/dev/ad0a
Mounting root from ufs:/dev/ad0a
WARNING / was not properly dismounted
Enter full pathname of shell or RETURN for /bin/sh:
The line "Enter full pathname of shell or RETURN for /bin/sh:" seemed to be rather grayed out. What I mean is that the color is a bit lighter than the other text above of it.
At this point I can't type anything. It's pretty much frozen.
Scenario 2:
----------------
After I power cycle the array, it boots up and comes to this:
F1 FreeBSD
F2 FreeBSD
F3 FreeBSD
F5 Drive 1
Default: F5
I NOT touch anything on the keyboard and it changes to this:
F1 FreeBSD
F2 FreeBSD
F3 FreeBSD
F5 Drive 2
Default: F1
I let it boot up and hit space after a sec or so.
then I get it down to the ok prompt:
ok
I type
ok boot -s
It boots up and here are the lines before I hit my road block:
Waiting for DAG engine to start
RAIDFRAME: configure (RAID level 1): total number of sectors 483200 (235MB)
RAIDFRAME (RAID level 1): use 6 floating recon bufs with no head sep limit
Mounting root form ufs:/dev/raid0c
Enter full pathname of shell or RETURN for /bin/sh:
At this point I can't type anything. It's pretty much frozen.
I don't know what to do at this point.

Mukarram,
What does it say in the 2-3 lines above the shell path request? That's
important information to help you get past it.
Sometimes pressing control-D will skip you past it (after you press enter).
Please advise,
Ryan
