610# The flags takes the following meaning for apm0:
611# 0x0020 Statclock is broken.
612# If apm is omitted, some systems require sysctl kern.timecounter.method=1
613# for correct timekeeping.
614
615# Notes on the spigot:
616# The video spigot is at 0xad6. This port address can not be changed.
617# The irq values may only be 10, 11, or 15
618# I/O memory is an 8kb region. Possible values are:
619# 0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
620# The start address must be on an even boundary.
621# Add the following option if you want to allow non-root users to be able
622# to access the spigot. This option is not secure because it allows users
623# direct access to the I/O page.
624# options SPIGOT_UNSECURE
625
626# Notes on the Specialix SI/XIO driver:
627# The host card is memory, not IO mapped.
628# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
629# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
630# The cards can use an IRQ of 11, 12 or 15.
631
632# Notes on the Sony Programmable I/O controller
633# This is a temporary driver that should someday be replaced by something
634# that hooks into the ACPI layer. The device is hooked to the PIIX4's
635# General Device 10 decoder, which means you have to fiddle with PCI
636# registers to map it in, even though it is otherwise treated here as
637# an ISA device. At the moment, the driver polls, although the device
638# is capable of generating interrupts. It largely undocumented.
639# The port location in the hint is where you WANT the device to be
640# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
641# is the only thing truly supported, but aparently a fair percentage
642# of the Vaio extra features are controlled by this device.
643
644# Notes on the Stallion stl and stli drivers:
645# See src/i386/isa/README.stl for complete instructions.
646# This is version 0.0.5alpha, unsupported by Stallion.
647# The stl driver has a secondary IO port hard coded at 0x280. You need
648# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
649# The "flags" and "msize" settings on the stli driver depend on the board:
650# EasyConnection 8/64 ISA: flags 23 msize 0x1000
651# EasyConnection 8/64 EISA: flags 24 msize 0x10000
652# EasyConnection 8/64 MCA: flags 25 msize 0x1000
653# ONboard ISA: flags 4 msize 0x10000
654# ONboard EISA: flags 7 msize 0x10000
655# ONboard MCA: flags 3 msize 0x10000
656# Brumby: flags 2 msize 0x4000

658
659# Notes on the Digiboard PC/Xi and PC/Xe series driver
660#
661# The NDGBPORTS option specifies the number of ports controlled by the
662# dgb(4) driver. The default value is 16 ports per device.
663#

665# 0x01 - alternate layout of pins

606# The video spigot is at 0xad6. This port address can not be changed.
607# The irq values may only be 10, 11, or 15
608# I/O memory is an 8kb region. Possible values are:

612# to access the spigot. This option is not secure because it allows users
613# direct access to the I/O page.

616# Notes on the Specialix SI/XIO driver:

622# Notes on the Sony Programmable I/O controller
623# This is a temporary driver that should someday be replaced by something
624# that hooks into the ACPI layer. The device is hooked to the PIIX4's
625# General Device 10 decoder, which means you have to fiddle with PCI
626# registers to map it in, even though it is otherwise treated here as
627# an ISA device. At the moment, the driver polls, although the device
628# is capable of generating interrupts. It largely undocumented.
629# The port location in the hint is where you WANT the device to be
630# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
631# is the only thing truly supported, but aparently a fair percentage
632# of the Vaio extra features are controlled by this device.
633
634# Notes on the Stallion stl and stli drivers:
635# See src/i386/isa/README.stl for complete instructions.
636# This is version 0.0.5alpha, unsupported by Stallion.
637# The stl driver has a secondary IO port hard coded at 0x280. You need
638# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
639# The "flags" and "msize" settings on the stli driver depend on the board:
640# EasyConnection 8/64 ISA: flags 23 msize 0x1000
641# EasyConnection 8/64 EISA: flags 24 msize 0x10000
