I have (finally) located the ancient server that has the rom code for 
the MIPS based Cobalt products.  The ROM itself does just enough to boot 
a very small Linux kernel stored in the rom, which in turn loads the 
kernel to boot from the disk.  That's it: the rom does just enough to 
get the kernel loaded.

I don't see anything that looks like clearing bss, but then I don't read 
GAS code very well:
	*(.dynbss)
	*(.bss)
	*(COMMON)

is all I see.

HTH,
