Sector layout question

[Khumba]

Hello. I was wondering if anyone knows of a website
that has a complete memory map. Like one that shows
that the screen memory starts at 0xb8000, to what
sector boot code is loaded, what sectors are available
for code and data, etc. Please tell me if you know.
Thanks ahead of time!

ints are at 0x0, and extend for 256*4
Video memory is 64k from 0x000a0000
text video memory is at either 0x000b0000 or
0x000b8000 depending on wether the card is
colour or monochrome.
Boot sector is loaded at 0x0007c000, if I recall
correctly.

Other than that, everything's pretty much available...
If you're thinking about for bootup, its not like you
need much space... I simply use anything
above 0x00010000 but before 0x000a0000. You should
be safe with that.
