Friends,

Are all SPARC machine capable of booting into both 32 bit and 64 bit?

How do we find whether a SPARC machine is capable of booting in 32 bit.

Any pointers would be of great help. Please let me know if you need more specifics on this.

Right now these machined are running on 64 bit, But how to find whether the m/c is capable of booting in both 32 or 64 bit?

32 bit machines can not run 64 bit OS. What is your system model?

Thankx. It is currently running with 64 bit OS (Which is fine).

My question is a little different. Would appreciate if you could let me know the following

- Is it possible to booth this Sun-Fire-V210 with 32 bit OS?
- If so, what would be the steps?
