Multi-boot 32/64 bit 1

[strider952]

All,

I have some test systems I need to be able to boot into both 32 and 64 bit. One is a "C" class, the other a "J" class.

1. Can these systems be booted into 32 bit mode?
2. getconf KERNEL_BITS returns a 64. Is it already too late to set up these installations as multi-boot?
3. Is it possible to have a multi-boot situation?
4. If I install it correctly, how do you switch between the two?

TIA!

oops...I was just glancing through the 11.0 install guide. The output of my "model" commands are:
9000/785/C3600
9000/785/J5000

Does this mean these systems CAN'T run 11.0 32-bit?
