I mean where can I find the information from which

"* It then loads 'setup' directly after itself (0x90200), and the system
* at 0x10000, using BIOS interrupts. "
-- bootsect.S

The ability to know how to get the BIOS to do that comes from, e.g. a
book that can tell me how to do that without taking another degree...
Where the information can be found, that says what BIOS memory
area 0x90200 is for etc.
