New Grappler SCSI Controller Firmware

for 906F, 930U and 940UW models were released by Orange Micro for download here. [Version Tracker] However,WARNING! I updated my 930U's firmware from 1.18 to 1.22 and got a gray screen on restart, nothing else. I can only startup my B&W G3/300 by disconnecting my external SCSI chain containing a SyJet and UMAX 1200S scanner. The internal SCSI hard drive connected to the 930U still works. Both the internal and external devices worked fine before the firmware update--why did I do this? I sent an inquiry to Orange Micro.
