I'm using a ZuluSCSI Pico slim on one of my SE/30s. The Zulu firmware complains about one of the images having a LIDO SCSI driver and warns of potential problems. But, regardless of how I try to come at it I'm unable to 'UPDATE' (replace the SCSI driver) on that volume. I know that one cannot generally update the boot volume, but even after booting from a different volume the UPDATE button is grayed out. I am using a patched version of Apple HD SC Setup 7.3.5 which has no problem seeing the drive.
