Hi, Could anyone answer few questions on bootup sequence of linux that i have.
1.What is the typical size of a bootloader? Since the booloader code starts from 0x7c00 and can touch till 0x9A000, Can i assume that the max size of the bootloader could be 0x9a000-0x7c00=0x92400[ 585kb ]. What if the bootloader exceeds this size?
2.Will the bootloader use the magic number of the(0xAA55) of the kernel header? If so, when?
- Is the BIOS setting the IVT for loading linux standardised? (I asked the because some vector numbers are used by the bootloader BIOS calls). If so, where can i get the details?
Thanks Uday
