1.1 ! root 1: SSCCSSII -- Device Driver ! 2: ! 3: ! 4: The COHERENT SCSI series of device drivers lets you use SCSI-interface ! 5: devices attached to host adapters from several vendors. ! 6: ! 7: All COHERENT SCSI device drivers use major number 13, thus allowing all ! 8: SCSI devices to be accessed via standard device-naming conventions. ! 9: Peripherals can be accessed as either block- or character-special devices. ! 10: The minor number specifies the device and partition number for disk-type ! 11: devices; this allows the use of up to eight SCSI identifiers (SCSI-ID's), ! 12: with up to four logical unit numbers (LUNs) per SCSI-ID and up to four ! 13: partitions per LUN. Tape and other special devices decode the minor number ! 14: to perform special operations such as ``rewind on close'' or ``no rewind on ! 15: close''. ! 16: ! 17: The first ooppeenn call on a SCSI disk device allocates memory for the ! 18: partition table and reads it into memory. ! 19: ! 20: See the release notes for further information regarding supported host ! 21: adapters and peripherals. ! 22: ! 23: _F_i_l_e_s ! 24: /ddeevv/ssdd* -- block-special devices ! 25: /ddeevv/rrssdd* -- character-special devices ! 26: ! 27: _S_e_e _A_l_s_o ! 28: aahhaa115544xx, ddeevviiccee ddrriivveerrss, ddrrvvlldd, ssss ! 29: ! 30: _N_o_t_e_s ! 31: The Mark Williams Company's bulletin board makes available device drivers ! 32: for various SCSI host adapters, as well as device driver updates.
