Which compilers should i use for....

is GCC the best compilers to use if i want to programm a little OS??

and one thing....a lot of people are telling me i can't develop the os in WindowXP. why not?? because i want to do some coding with DEV C++ / GCC in WinXP and test it later..... ( while i am listening to MP3s.... ^_^)

Any body has the answer to that??

Well I was reading tutorials about writing kernels and operating systems (and followed them) @ www.osdev.com and check out the links and they all said to use GCC for writing the C code and NASM for writing the hardware interface in assembler. And about XP I don't know because I will not use it I change my hardware and format my hard drive too much to follow the restrictions unless I get the big business version.

if you could write or find some sort of bios only machine emulator then i see no reason why you should not be able to test the bootloader and kernal.

Why exactly do you want to write the OS in XP anyway? you could always load a different version of windows or even LINUX, BeOS, or another free OS.
