Our website provided a free download of Apple Ultra2 SCSI Card Firmware 1.2 for Mac.
From the developer:
If your (blue and white) Power Mac G3 or Mac Server G3 came with a single channel Ultra2 low voltage differential (LVD) SCSI card, run the "2940U2B v1.2 Flash Utility" to install updated firmware on the card to increase performance and reduce compatibility issues when using large files.
