6 | + | ||
7 | + Added option to read in bootcode from a file so that if you have | ||
8 | + for example Windows 2000 boot code, you can have it write that | ||
9 | + as the bootcode. This is a dump of the behinning of a partition | ||
10 | + generally 512 bytes, but can be up to reserved sectors*512 bytes. | ||
11 | + Also writes 0x80 as the BIOS drive number if we are formatting a | ||
12 | + hard drive, and sets the number of hidden sectors to be the | ||
13 | + number of sectors in one track. These were required so that DOS | ||
14 | + could boot using the bootcode. | ||
