Final answer:
BootX is the default boot loader for Mac OS X, specifically for PowerPC-based Apple computers. It supports various file systems for loading kernels and is not exactly similar to BIOS.
Step-by-step explanation:
The statement that is true about BootX is that BootX is the default boot loader for Mac OS X. BootX is responsible for loading the Mac OS X operating system on PowerPC-based Apple computers until it was replaced by other booting mechanisms in later systems. BootX does indeed support loading kernels from file systems including HFS, HFS+, UFS, ext2, and can also boot over the network using TFTP.
Therefore, the correct answer is that Option 1 is true, while Option 2 is false. Comparing BootX to BIOS is not entirely accurate, as the BIOS (Basic Input/Output System) is a low-level software that initializes and tests the system's hardware components and boots a computer's operating system from the PC-compatible systems, whereas BootX is much more specific to Mac OS X on PowerPC architectures.
