add on board support
note: if you inclide the gfx framebuffer support in the kernel, then you CAN NOT boot with missing gfx hw board! The kernel is expecting to find it, if it is missing it will panic!

Suggestion: do not include the framebuffer, use uart console only

kernel status
removing - Tickless System (Dynamic Ticks) - High Resolution Timer Support - SCSI generic support - RAID Transport Class - Verbose SCSI error reporting (kernel size +=12K) - SCSI logging facility
 * note1

forcing - No Forced Preemption - SCSI_WAIT_SCAN compiled as builtin (it was an hidden module)

about sgi o2

Known working PCI cards with IRIX

 * SGI PCI Serial I/O a.k.a. PCI SIO UFC, part number 030-1657-003, Provides two RS-232/RS-422 serial ports. The board is slotted for universal voltage, but SGI only provides drivers for Onyx 300/350/3000 systems. The SGI marketing code is PCI-SER-10002.
 * SGI PCI Digital Audio Board . The SGI part number for the example shown is 030-1649-001, it appears in an hinv with PCI vendor ID 0x10a9(SGI) and a device ID of 0x0005(RAD Audio):
 * SGI PCI Gigabit Ethernet:, 1000 Base SX (fiber optic interface) and 1000 Base T (copper interface) - shown mounted in an O2k XIO Shoehorn : Both are keyed as 'universal' PCI cards to fit in either 3.3 or 5 volt slots.
 * SGI O2 10/100BaseT Network Card for O2: SGI marketing code SGI_PCI-ENET-TX-1P; part number 9210105
 * SGI USB PCI card, SGI part number 9210286: NEC chipset - Slotted for 3.3 and 5V PCI applications. SGI equipped Onyx 350 InfiniteReality and InfinitePerformance systems with this card as an attachment point for USB keyboards and mice. There are some references on TechPubs indicating Orange Micro as the OEM, while "UP205-0525" screened on the PCB returns Adaptec references. It appears in an hinv with a PCI vendor ID of 0x1033 (NEC) PCI device numbers 0x0035(Dual OHCI controllers plus Single EHCI controller) and 0x00e0(USB 2.0 Host Controller).
 * DATAFIRE PCI 1ST ISDN card SGI PN: 9210111 Came inside one O2, SGI part number 9981028 SGI

Things to keep in mind when building kernel for an SGI Octane

 * Impact (MGRAS) console and X driver work, please report any bugs.
 * VPro (Odyssey) console works, but no X driver exists yet.
 * PCI Card Cages should work for many devices, except certain types like
 * PCI-to-PCI bridges (USB hubs, USB flash card readers for example).
 * Do not use OHCI-based USB cards in Octane. They're broke on this machine.
 * Patches are welcome to fix the issue.
 * Equally, UHCI Cards are showing issues in this release, but should still function somewhat. This issue manifests itself when using pl2303 USB->Serial adapters.
 * Other XIO-based devices like MENET and various Impact addons remain
 * untested and are not guaranteed to work. This applies to various digital video conversion boards as well.

add on board support
What is the state of hardware support on this machine?


 * V6, V8 gfx: X11 support doesn't exist, and likely won't for a very long while. Stan (the IP30 Port Author) recently got console mode running on this card, but from what I understand, this is a rather complex piece of video hardware. Remote X works, however.
 * Impact gfx: X11 is working
 * Onboard sound works well enough from what I hear. I tested several MP3s from console via mpg123, and they worked well. A new patch coming out next week (Jul 23-24) will enable support for the optical inputs/outputs for AES (ADAT capabilities will not be supported).
 * Onboard Scsi works like a charm. It wasn't entirely usable about 3 weeks ago due to reliance on the old qlogicisp driver, but with some very recent fixes to qla1280, it has replaced qlogicisp. I now run a RAID5 array using 3 50G seagate drives on my Octane, and so far, everything works great (and hdparm reports ~17.4MB/s throughput).
 * Onboard Ethernet works fine too. The IOC3 driver was recently re-written to make IOC3 more of a Bus device with peripherals hanging off of it, which makes IOC3 less of a nightmare device from a coder's standpoint (but not by much).

boot examples

 * booting openbsd

= dual boot, idea =

It should be possible if you set up IRIX as per normal and leave space on the drive for Linux. Install Linux as per the guide except when you get to set up the PROM. you'll want to leave that as is. Then you'd set up arcload to boot up Linux on demand.


 * To boot IRIX, just switch the machine on.
 * To boot Linux, drop to the monitor prompt and run boot -f arcload.
