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. -- ______________________________________________ http://www.linuxmail.org/ Now with e-mail forwarding for only US$5.95/yr
