Hi,

I just got the new iMac and I would like to know what tools I need to OS proramming?

Thanks!

You've probably already got everything:
The GCC compiler suite and binutils would cover pretty much everything.

You'll probably also want a PC emulator like QEmu, Bochs, or VMWare.

I've used all, and I like QEmu for most everything, but Bochs allows better debugging.

I didn't think VMWare ran on OSX. It's one of the Intel based Macs right? The only computer emulator that I know for sure works on x86 Macs is called Parallels. Parallels isn't free though.

Bumping this thread...

I've managed to create a GCC cross-compiler on OS X. My OS compiles ok and runs under Parallels (not that it does much, but there it is anyway)...

So yes, it is possible! Although I have noticed that Parallels, like Virtual PC, has limited VGA emulation... no 90x60 text mode and custom font for me

There's a native Cocoa port of Qemu for OS X called 'Q' that seems to work fine for me so far. Google around for that...

Akin to this, it is probably also possible to use your OS on a mac, without emulation.

If you use the BIOS, then use Boot Camp and put your OS disk in instead. Use rEFIt for a bootloader.

GUID or whatever Apple uses is probably accessable if you use EFI, not the BIOS (what mactels natively use (EFI that is)) - but being a noob I don't know.

Perhaps someone should code a BIOS/EFI abstraction layer.

Right now I'm using GRUB, my iMac doesn't have a floppy drive, and I haven't had the time to figure out floppy emulation with a USB key... I haven't even installed Boot Camp yet, so I'm a long way from booting my OS on the raw Mac hardware.
