how do I tell if I have a 32 bit system or a 64 bit?

Functional test:

test booting with a live CD of each type --- a 32 bit only capable processor will 'choke' on the 64 bit CD -- the 64 will handle either. SO .. a 32 bit CD will boot on either type of hardware

'Read the label' test

Once the unit is up with a 32 bit CD, inspect the processor strings and verify at the vendor's

cat /proc/cpuinfo

If it is a unit with a vendor provided 'build sheet' it may call out the specific processor and stepping, but be wary here --- some hardware manufacturer's disable capabilities the processor has ... Laptops particularly may have a virtualizaion capable processor, but such is disabled often
