The intermediary piece of program code run between the ROM-BIOS and the actual OS while booting. >How do you write a file to boot sector ? You can't put files in there, it is too small. You can look at or modify it with the Norton Utilities disk editor (at least the DOS ones) or better with a:\dos\debug.com from any old DOS floppy. >can we write to boot sector with Visaul Basic 5 ? No, you must use Assembler for boot sectors. In fact they are one of the last things you must use Assembler for. Even Linux does so. >What code is in boot sector ? Binary code ? or normal text ? C program code >? Dos command ? ...... Pure binary. And a bit of data. > i'm 11 year's old , i'm just corious. That is the ideal age to start hacking. I was late with 16 (in 1981). blazing.psyco@hell.4U.com (Blazing Psycho) was unfriendly: >Get ye disk edit, bairn!! Hey Psycho, we have here what looks like a real hopefull fledgling Hacker. Treat the few of them still around well. Or do you want yet more Crackers, Warez and XXX lamers around here? Actually bootsectors are a good entry path into groking how computers work. Orang-utan get yourself - an old DOS floppy with 2.11, 3.3 or 5.0. 3.3 is prefered - an equally old DOS manual that describes using the debug.com program - an old DOS system architecture book (such as [1]) - an 8088 Assembler manual Then have a good hack. Later progress into Linux.
