The collected works of zulu5d

I've tried reading how to from comp.sys.sgi and, apart from the posters not being able to agree on anything, does anyone here have a "simple" explanation on how to burn a disk to get the first installation disk to boot!

Any help appreciated!
Thanks for your input. I've always been netbooting live updates but have always been curious as to how to....... Wonder how SGI do it for their CD's?
