Read the fucking manual. Tell us what the fuck you've got.
\r\n\r\n[link|http://www.debian.org/releases/stable/mips/install|Installing Debian GNU/Linux 3.0 For Mips]. Looks like you're going to want the TFTP or NFS boot methods, but you should read the [link|http://www.debian.org/releases/stable/mips/ch-rescue-boot.en.html|Booting the Installation System ] section. Another suggestion is [link|http://www.linux-mips.org/index.html|The Linux MIPS Project].
\r\n\r\nI know this is hard for you, Box, but a modicum of specificity on the system you've got -- model, approximate manufacture date, version of Irix, memory, disk -- would be useful. I'm guesing an Octane, Indy, or O2, but that's coming straight out of /dev/ass.
\r\n\r\nI'll also suggest you make liberal, but appropriate, use of the .,:;? and <shift> and <enter> keys on your next post if you expect a reply from me.
