New Revision: 52253
URL: http://svn.reactos.org/svn/reactos?rev=52253&view=rev
Log:
[FREELDR]
- Add underscore to names of trap handlers and add C prototypes (will be needed later)
- Move multiboot code to seperate file multiboot.S, not compiled atm, the code wasn't
in use anyway
- Remove EnableA20 dummy
Added:
