Hello Linus,
Can you tell me where this magic address 0x78 in arch/i386/bootsect.S
refers to? I mean, is this somewhere specified?
Many thanks and cheers from germany.

Hope you'll settle for an answer from a simple lkml lurker and not the top
gun.
The address 0x78 points to the floppy disk drive parameter table
described here: http://www.xs4all.nl/~matrix/fdd_pt.html
A list of all the low memory ROM BIOS vectors and addresses can be
found here: http://www.cybertrails.com/~fys/rombios.htm
Cheers,
Sean

I believe Tigran's Linux Kernel Internels guide for 2.4 covers this, you can
download it from here:

Alas, there isn't a 2.5 guide yet. Moves too fast. :)

Hello Sean,
