Understanding Grub' internals
Posted: Wed Sep 05, 2007 3:10 pm
I want my operating system, or what will be an operating system (2 more weeks and version 0.01 will be released) to boot from my laptop. But being a turion, then a 64 bit architecture, the engineers treated low memory for low memory. The himem (more than 1mb) memory that 286 era people were talking about is no more. In this world of multicore, multigigahertz machine with multigigabytes of ram to spare, memore below 16 meg is low memory.
But how to keep my kernel lighweight on lowend systems as my new aptiva and be compatible with my "highend" laptop.
THe answer: grub. But I DON'T want to USE grub!
Don't worry, just study the code. But it's boring
There's an interrupt to read the ram partitioning, so I could use that.
edit. OK, I think I have found something.
