Re: Easy words for boot sector ?
Posted by: ggn Mar,15.2017-10:54 

I wrote a few words about bootsectors in some random diskmag, perhaps you know it? http://alive.atari.org/alive10/dim2st.php

;)

Long story short, a valid bootsector (and yes, it is the disk's first sector) is 512 bytes long but if you want to be system friendly (i.e. you want the disk to be recognised by TOS and disk copiers etc) you have to exclude some bytes - so you're left with 480 bytes to play. The absolute minimum number of bytes for an instruction on 68000 is 2 bytes so you have at most 240 instructions to play with.
