Dear all:
A quick question for loader prompt in FreeBSD OS.
Recently i do some benchmarking in the FreeBSD OS, and today i decide
to enable some
performance tools in the kernel which can be realized by building a new
kernel.
Before that, i refer to the FreeBSD handbook for howto.
It says that if i fail to load the new kernel, we can select the
"escape to a loader prompt" option.
By loading the correct kernel, we can reboot the system.
However, problem happens. When i select the "escape to a loader prompt"
option, i can input
in about just 3 sec. After that, the system cannot go on whatever key i
hit.
The whole system have 4 hard disks; and i install 3 OSes in the first 3
hard disks which are
Linux, Solaris and FreeBSD in order. All systems are booted using grub.
Any ideas?
Best Wishes!
Yan
