How to get in multi-user mode on ramdisk kernel?

["Boo Geum Jung" <bgjung%etri.re.kr@localhost>]

The previous problem (system halt after # prompt) was due to wrong
assignement of irq of com0.

I succeeded in executing ramdisk kernel.

=============================
.....
biomask 0 netmask 38 ttymask 38
md0: internal 2048 KB image area
boot device: <unknown>
root on md0a dumps on md0b
WARNING: invalid time in clock chip
WARNING: CHECK AND RESET THE DATE!
root file system type: ffs
erase ^H, werase ^W, kill ^U, intr ^C, status ^T
Terminal type? [vt100] vt100
Erase is backspace.
(I)nstall, (S)hell or (H)alt ? s
#
# exit
#
#

"exit" had no effect.
I prepared all files like hosts, rc.conf, ifconfig, resolve.conf in
ramdisk.fs for multi-user processing.
I can't find how to get in multi-user mode on ramdisk kernel?
