Whoa! I don't believe that I woulda tried that. Well I am not really a Sun guy and I have never used Solaris 7. Still I will make a few wild guesses. Remember though, no money back guarantee or anything...

My guess is that the OS can't get far enough into the boot processes to run the scripts that a reconfig boot would invoke. So you have a chicken and egg problem. I can think of two things that might be worth a try. I don't understand either of them well and in fact I would need to flip a coin to pick which to try first.

First, /etc/system has some comments in it talking about setting the parameter rootdev to override the root device. Take a look at your /etc/system and look at the commented example of setting the root device. You might try that.

Next, if you can get into single user mode, you might try running the stuff that a reconfigure reboot would run. The things that look appropriate are:
drvconfig
devlinks
disks

Well good luck, dude, you're gonna need it. If you get that thing up to multi-user mode, let us know what did the trick.

VPO(4)							   BSD Kernel Interfaces Manual 						    VPO(4)

NAME

     vpo -- parallel to SCSI interface driver

SYNOPSIS

     device vpo

     For one or more SCSI busses:
     device scbus

DESCRIPTION

     The vpo driver provide access to parallel port Iomega Zip and Jaz drives.

HARDWARE

     The vpo driver supports the following parallel to SCSI interfaces:

     o	 Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP drives)
     o	 Iomega Jaz Traveller interface
     o	 Iomega MatchMaker SCSI interface (built-in to Iomega ZIP+ drives)

USAGE

     The driver should let you use a printer connected to the drive while transferring data.

     DOS and FreeBSD file systems are supported.  When mounting a DOS file system or formatting a FreeBSD file system, check the slice of the disk
     with the fdisk(8) utility.

     In order to unixify a ZIP disk, put the following in /etc/disktab:

     zip|zip 100:
	     :ty=removable:se#512:nc#96:nt#64:ns#32:
	     :pa#196608:oa#0:ba#4096:fa#512:
	     :pb#196608:ob#0:bb#4096:fb#512:
	     :pc#196608:oc#0:bc#4096:fc#512:

     and use bsdlabel(8).

     If you have trouble with your driver, your parallel chipset may not run properly at the detected mode (NIBBLE, PS2 or EPP).  Tune the ppc(4)
     bootflags to force other modes.

SEE ALSO

     da(4), lpt(4), ppbus(4), ppc(4), scsi(4)

HISTORY

     The vpo manual page first appeared in FreeBSD 3.0.

AUTHORS

     This manual page was written by Nicolas Souchu.

BUGS

     During boot, the driver first tries to detect a classic ZIP, then a ZIP+.	The ZIP+ detection is intrusive and may send erroneous characters
     to your printer if the drive is not connected to your parallel port.
