How can I set the HTTP Brouser!?[/b]

Don't take this big chucks at once. HTTP browser is a big step

start with sample applications like *.asm files that came with MEnuetOS...

I would suggest starting out with the 32bit version of menuetos since there are more tutorials and resources concerning 32bit assembly available online.

For starters: read the (pdf)documentation that comes with fasm
(This isn't included on the MenuetOS diskette, visit http://flatassembler.net/)

Then check out example.asm and try to change some basic things like the displayed text/colors. (with the help of syscall.txt that you can find on the MenuetOS diskette)

MenuetOS (currently) only supports a handful of network cards. But you can still use localhost. Read all about it in stack.txt (on the diskette)
