I have an aged Ultra 20 (AMD) running Solaris 10 that boots fine as long as another hard drive has not been added to the bus; with the second drive added, I can't even get to BIOS settings, instead seeing "Sun Microsystems" logo, never getting any further. If secondary drive is formatted or unformatted, I have same results.
Any suggestions how to address this? I don't have a lot of experience with BIOS and/or hardware.
Cheers, Doug
