From the Big Book of Amiga Hardware:
The Guru ROM is a third party ROM (written by Ralph Babel, a former employee of GVP) containing replacement driver software for all GVP SCSI controllers in the \"Impact Series II\" class. The drivers provide improved performance and transfer speeds, bug fixes, work arounds for bugs in the A3000 and A4000 DMA handling and better support for modern SCSI devices.
GuruROM v6The GuruROM is a replacement driver for most Commodore (C=) and Great Valley Products (GVP) Zorro II DMA SCSI expansion card products based on their respective DMAC or DPRC custom-DMA controller chips for the A500 and A2000 platforms. This includes the 68030/68040 accelerator products by GVP and also the GVP A1208 trapdoor module.The driver is sold as a kit; a ROM in an adapter. Three versions of the adapter have been produced. The first version was two controller-specific adapters with a 32K (27C256) EPROM - one for GVP boards, one for C= boards. The second (latest) version supports both controllers with one adapter. It has a jumper to select the matching adapter image from the 64K (27C512) EPROM, and is loosely referred to as the omni-adapter. All adapters have a custom logic GAL to permit the driver code (32K in approximate size) to be read into the system within a 16K address space provided for on each host adapter. Both native driver ROMs for each card are 16K, and therefore do not need this additional logic.
