NAME # ioasic - baseboard IO control ASIC for DEC TURBOchannel systems
SYNOPSIS # ioasic0 at tc? slot ? offset ?
DESCRIPTION # The ioasic driver provides support for the DEC proprietary IOCTL ASIC found on DEC 3000 TURBOchannel machines.
The ioasic provides hardware DMA channels and interrupt support for several baseboard devices, including one asc(4) SCSI device with a scatter/gather DMA channel, an mc146818-compatible mcclock, an Am7930 audio device bba(4), two zs(4) dual-port serial devices, and an AMD 7990 LANCE le(4) Ethernet interface.
