Hello

I'm absolutely new to Netbsd and to the Sun architecture.
I'm trying to install NetBSD to a SunIPC station that I just got, I tried to follow the instructions in the Install.html file, but wasn't able since I didn't find the set_name.xx files, not even the /Split directory (I downloaded from netbsd.org, the whole sparc subdirectory).
I'm downloading the CD ISO Image now I have a few questions, though. 

When booting into the PROM I get many error messages, that may suggest the machine is broken (or maybe just that it's battery, if it has one, has died). The most intriguing are:
Incorrect configuration checksum, I get this right after the "Starting Real time clock"
Ethernet address ff:ff:ff:ff:ff:ff, Host ID ffffffff. I really don't think the computer uses the broadcast ethernet address to receive, so there must be something wrong. My theories are software will later change that address to something logical or the built in NIC had some info stored in EPROM and it somehow died. Can I fix that?

The IDPROM contents are invalid

Those are the messages that look like a hardware problem. Can somebody help?

I'm planing on using an external SCSI CD to install since floppied failed, will any SCSI CD do? I was thinking of using CD-R that I already have mounted into an external case, can I use that? Is that recommended?
If everything fails, isn't there someway I could take out the HDD, conect it to my PC running Linux or FreeBSD and install from there? and then reinstall the HDD into the IPC box?

Thanks in advance for the info you may provide
