DO MAC Computers have BIOS?

Because most Mac computers that i tried in the past, it never shows BIOS, but with an ordinary Computer with a windows operating system, always shows the BIOS software...and then loads the OS...

but with MAC computers, you never see the BIOS!

it just goes directly into the Operating system

MAC OS X

Open Firmware is the BIOS used by Apple systems, and is used to provide low-level control to some

parts of the hardware. Open Firmware uses a command line driven interface more similar to that

used by Sun Microsystems than the graphical BIOS used by x86 PCs.
PowerPC based Macs use Open Firmware, which can be accessed by pressing Cmd-Option-O-F at Startup
They don't in the traditional idea of what a PC computer BIOS is, but there is a boot system running in the background.
