- README for hardware subtree
-
-
- A subtree of information useful for our hardware developers. At present
- this tree contains:
-
- ---> `!', indicates new or updated as of v4.1 of the Toolbox
-
- ! dat : This sample driver source code is for provided to give
- you an example of how to use dslib routines. It is NOT
- the aim of this driver to replace the tape driver in
- IRIX nor it is to be used INSTEAD of that driver. It
- is simply a working user-level driver to be used and
- studied as an example of interfacing with the Scsi bus
- through routines in dslib library.
-
- HDW.faq : "Frequently Asked Questions" about hardware issues.
-
- Hardware.FAQ : the most recent SGI Hardware Frequently Asked Questions
- maintained by Allan Schaeffer and posted to various
- internet news groups as well as a list of questions and
- answers culled from the last 1800 messages (as of late
- October, 1993) to comp.sys.sgi.hardware.
-
- GIO_DRVR4.0.5: GIO Device Driver Writing Guide. The files in this
- directory contain information needed to write a device
- driver for a GIO board on an Irix 4.0.5 system software
- platform.
-
- GIO_DRVR5.1 : GIO Device Driver Writing Guide. The files in this
- directory contain information needed to write a device
- driver for a GIO board on an Irix 5.1 system software
- platform.
-
- ! h550_driver : NOTE that THIS DRIVER will ONLY OPERATE ON IRIX 5.2 or
- later. Contains the source for an in-process project of
- writing a device driver for the Comtrol Hostess 550
- Serial Port Board. The board can have either 4 our 8
- ports per card. The UART chip used on the board is a
- 16550.
-
- mount_media : two sets of programs in this tree allow user mounting
- of either a CD-ROM or a Magneto-Optic (MO) drive to an
- SGI system. Normally a user would have to have root
- access to mount any device. These two programs allow
- any user to do this.
-
- ! monitorCalibration: information on how to calibrate the new Sony
- monitors.
-
- parallel_port: contains an example of how to program for the parallel
- port. (more to come...)
-
- ! rap : Roland RAP-10 Music Card Device Driver for Eisa Bus
- contains a sample device driver for IRIX 5.2 EISA bus,
- demonstrating:
- * Writing a character device driver for EISA bus,
- * How to obtain an Interrupt number (IRQ),
- * How to allocate and program EISA DMA chipsets,
- * How to program Eisa Dma channels for hardware
- recognition,
- * How to use EISA Dma chips to move data from/to a
- device,
- * How to manage and use a circular buffers between
- kernel and user's read/write calls,
- * and many more ...
-
- summa : contains all the files required to build and test the
- Summagraphics 6x9 tablet driver. This could be used
- as an example of how to create a streams device driver
- for a typical serial port device.
-
- video : at present contains a postscript file describing the
- SGI Digital Video specification including the data
- format, electrical and mechanical interfaces used to
- get digital video data into and out of the Silicon
- Graphics platforms via this 60-pin connector.
-
- VMEdoc : VME interface description for Personal Iris, 4D100 to
- 4D400 series machines, and Crimsons. This paper does
- NOT include the IO4 VME in Challenge and Onyx systems.
-
-
- In time we will be creating a considerable portion of on-line information
- and source files useful to those working in the hardware areas of
- development.
-
-
- As we have asked in a recent survey,
-
- What on-line hardware-related information would be useful to you
- as a developer?
-
- What hardware-related tools and/or utilities would you find
- useful as a developer?
-
- What are the three most difficult development issues you face
- in making your product available for Silicon Graphics' platforms?
-
-
- WE WANT TO HEAR FROM YOU! If you have ANY responses to the above questions,
