Cirrus Logics pcic controller. Compatible with the i82365SL Step C with the addition of a different 3.3V control.
Ricoh RF5C296 Ricoh RF5C396
Ricohs PC Card bridge chips. These are compatible with the i82365SL Step C, but with yet another different 3.3V control.
Vadem 365 Vadem 465
Compatible with i82365SL Step C.
Vadem 468 Vadem 469
Like the earlier Vadem models, but with Vadems own, incompatible, 3.3V control system.
IBM clone of the original i82365SL part, with its own ID register value. Has no 3.3V ability.
A strange clone of i82365SL. This part has many restrictions not found in the i82365SL, plus some strange power control. It has not been tested in ages, but is believed to work. Its use is believed to be confined to model of ISA card, available only in Japan.
Many other vendors made parts in this arena, but most of them were compatible with one of the above chipsets.
The following PCI cardbus and pcmcia bridges are supported:
Cirrus Logic PD6729 Cirrus Logic PD6730
These chips require special configuration when they are on an add-in PCI card.
Needed for some, improperly manufactured PCI cards made by Orinoco. It disables function 1 completely. Set to 0 to enable function 1. Set to 1 to disable function 1. This tunable generally should not be needed on laptops. The default is 0.
Some machines can tolerate interrupt routing selection at the cardbus bridge level. Others fail when you mess with these registers. Set to 1 to force the chipset to route via parallel PCI interrupts (as well as a few other little things). Setting to 0, the default, forces the code to leave these registers as the code finds them. Most laptops will not need to set this tunable. Many PCI cards with cardbus chips on them are believed to need this tunable set to 1. The default is 0.
Should PCI pcic devices route interrupts via ISA or PCI. A value of 1 means route via ISA. A value of 2 means route via PCI. This is ignored for the ISA device. Many older laptops do not have PCI BIOS implementations that .Fx can use to route interrupts properly. These laptops may need to set this to 1 and hw.pcic.irq to a value (or 0 for polling). The default is 2.
Overrides the IRQ to use for ISA interrupt routing of the CSC or management interrupt. If you are using the ISA device, you can set this tunable, or use the .Cd "irq N" clause in config file. If you are using a PCI device in ISA interrupt mode (see hw.pcic.intr_path), then you must set the interrupt with this sysctl, or polling mode will be used. Due to limitations in the tunable system, only one interrupt can be selected for all cards. Systems with multiple PCI bridges that need to use ISA routing are encouraged to use polling mode on each of the cards. The default is 0.
Defaults to 0. Set to 1 to completely ignore the cardbus bridge. This may help some old laptops work. Setting to 1 on newer laptops will almost certainly fail.
