Title: Description of the boot procedure
Post by: Alexco on September 22, 2007, 10:56:39 PM

Hello!

I am searching for some information regarding the entire operations involved in a system boot (cold/warm). What does the hardware do, how are the vectors copied to address 0, what does exec when and how, in which order are devices, libs etc searched and found in ROM and so on.
Frankly, I have no clue whats going on up to the point where the boot screen is displayed.

Can someone help me out??

Thanks,
 Alex

ExecDis (http://aminet.net/package/dev/asm/ExecDis) on Aminet is a commented disassembly of exec 1.2 is a good start.
 Not a lot has changed in the coldstart of newer versions ( IIRC,a few minor differences for A3000/A4000 and CD32)

Piru has written a good account of what happens during a startup too,somewhere in this thread.. (http://www.amiga.org/forums/showthread.php?t=20698)
