NAME
ppc -- Parallel Port Chipset driver
SYNOPSIS
device ppc In /boot/device.hints: hint.ppc.0.at="isa" hint.ppc.0.irq="7" For one or more PPBUS busses: device ppbus
DESCRIPTION
The ppc driver provides low level support to various parallel port chipsets for the ppbus(4) system. During the probe phase, ppc detects parallel port chipsets and initial- izes private data according to their operating mode: COMPATIBLE, NIBBLE, PS/2, EPP, ECP and other mixed modes. If a mode is provided at startup through the flags variable of the boot interface, the operating mode of the chipset is forced according to flags and the hardware supported modes. During the attach phase, ppc allocates a ppbus structure, initializes it and calls the ppbus attach function. Supported flags bits 0-3: chipset forced mode(s) PPB_COMPATIBLE 0x0 /* Centronics compatible mode */ PPB_NIBBLE 0x1 /* reverse 4 bit mode */ PPB_PS2 0x2 /* PS/2 byte mode */ PPB_EPP 0x4 /* EPP mode, 32 bit */ PPB_ECP 0x8 /* ECP mode */ And any mixed values. bit 4: EPP protocol (0 EPP 1.9, 1 EPP 1.7) bit 5: activate IRQ (1 IRQ disabled, 0 IRQ enabled) bit 6: disable chipset specific detection bit 7: disable FIFO detection Supported chipsets Some parallel port chipsets are explicitly supported: detection and ini- tialisation code has been written according to their datasheets. o SMC FDC37C665GT and FDC37C666GT chipsets o Natsemi PC873xx-family (PC87332 and PC87306) o Winbond W83877xx-family (W83877F and W83877AF) o SMC-like chipsets with mixed modes (see ppbus(4)) of the flags boot variable is not null, then the operating mode is forced to the given mode and no other mode is available and ppb->ppb_avm field contains the available modes of the chipset.

BUGS
The chipset detection process may corrupt your chipset configuration. You may disable chipset specific detection by using the above flags.
