Getting a Sun 4/110 to boot

Greetings, After changing removing a jumper on my Sun 4/110's boot drive *running Solaris 2.4)so that it spins up with no motor control, I still can't get the system to boot from the CD-ROM as I did in the past when I originally installed the OS. I've disconnected all other hard drives and tape drives, so it's just the one hard drive and CD-ROM. The hard drive is SCSI ID 0, with terminating resistors, no parity, as it was before. The CD-ROM is SCSI ID 6, no parity (Toshiba XM-4101B). The hard drive was bootable, although it had lots of errors reported by fsck; when I ran fsck manually, I made a mistake that resulted in "device not found" when attempting to boot the system. Simple to fix, I thought... just reinstall the OS from CD-ROM as an "upgrade," thus preserving data on the drive (am I right about this part?). When I attempted to boot from the CD-ROM, b sd(0,6,n) and b sd(0,31,n) where I tried 0, 1 and 2 for n, the system tries to access the hard drive, as I can hear it trying to do so, in addition to the CD-ROM making a noise. Then, the following error message appears: sd: sense key=5 error=25, block 0 [repeated over and over, then:] Waiting for disk to spin up {and tells me to start it if necessary] Please start it, if necessary, -OR- press any key to quit sd: sense key=5 error=25, block 0 [keeps being repeated] Does anyone have any idea or suggestions? The next thing I'm going to try is to install another hard drive and try to install Solaris on it, but it seems to me that if I could boot from the present drive before the fsck mess, I should still be able to boot from the CD-ROM with that installed. Is there something I'm overlooking? -- R. D.
