i don't know about Guru Rom v6, but i read this at
aminet docs/rview/GuruROM.txt:
SOFTWARE INSTALLATION
The most important piece of software, the driver, is located in the
ROM chip, so there is no further installation necessary.
The utility and configuration software for advanced use on the
installation disk can be used right from the disk or copied manually to your
hard drive using Workbench or the Shell.
The configuration of all your software that uses the SCSI driver
directly has to be changed, because the new driver is called
"omniscsi.device" instead of "gvpscsi.device". This affects for example
DOSDrivers or Mountlist files, low-level disk utilities like HDToolBox or
SCSI-direct software like CD-DA players.
sorry, nothing more than that :angry:
