CyberVision 64/3D + CyberGraphX V3 + OS3.9 BB1+2

[MozzerFan]

If you installed boing bag 2, you either need to skip exec.library romupdate or you need to install CyberGFX 4.
See here for the explanation.

With Cybergrafx V3 you must replace your setpatch command
with the following:

SetPatch QUIET SKIPROMUPDATES "exec.library"

or if for example scsi.device is already skipped:

SetPatch QUIET SKIPROMUPDATES "exec.library,scsi.device"

[MozzerFan]

What if you change the setpatch command into the following:
c:setpatch noromupdate quiet

or

rename "Devs:amigaOs ROM update" to "Devs:AmigaOS ROM update.save"

Either way will skip the amiga romupdate. This worked for other users whose screenmodes disappeared with cgf3 under Os3.9 BB2.

If you use a harddisk greater than 4 gb, than you have to  split the amiga romupdate and load scsi.device of BB2 with loadmodule.
