Change size of terminal window?

[Rory Campbell-Lange <rory@campbell-lange.net>]

I'd like to change the size of the terminal window shown on screen.

I'm a Debian newbie. I've got Debian installed on our rather nice new
VALinux rackmount box and I've got it hooked up to a Mitsubishi TFT
flatscreen monitor. I don't have X running, and I'm doing everything in
text mode.

At the moment, while the "Intel" picture on startup uses the whole screen
fine, as soon as Lilo loads linux, the console fills only about 1/4 of the
area of the screen.

Sorry about the newbie question.
