boot hangs after install 4.8

[Rob Lahaye]

Hi,

I have just installed FreeBSD 4.8 on a PC. Only FreeBSD, no other OS.
The installation goes all well; I exit at the end and the PC boots.
Immediately after the BIOS stuff, I get the first FreeBSD prompt:


    F1  FreeBSD

    Default: F1


What ever key I hit next, only produces a beep from the PC.
Nothing happens, so it seems to hang at this point.

Any clue what is going wrong here?

Thanks,
Rob.
