|
||||
* Mark Lord <mlord@pobox.com>
|
||||
* Some parts of code are from ali14xx.c and from rz1000.c.
|
||||
*
|
||||
* OPTi is trademark of OPTi, Octek is trademark of Octek.
|
||||
*
|
||||
* I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
|
||||
* and disassembled/traced setupvic.exe (DOS program).
|
||||
* It increases kernel code about 2 kB.
|
||||
* I don't have this card no more, but I hope I can get some in case
|
||||
* of needed development.
|
||||
* My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
|
||||
* It has a place for a secondary connector in circuit, but nothing
|
||||
* is there. Also BIOS says no address for
|
||||
* secondary controller (see bellow in ide_init_opti621).
|
||||
* I've only tested this on my system, which only has one disk.
|
||||
* It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
|
||||
* is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
|
||||
* lockups). I tried the OCTEK double speed CD-ROM and
|
||||
* it does not work! But I can't boot DOS also, so it's probably
|
||||
* hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
|
||||
* problems) and Seagate 1GB (as slave, WD as master). My experiences
|
||||
* with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
|
||||
* it slows to about 100kB/s! I don't know why and I have
|
||||
* not this drive now, so I can't try it again.
|
||||
* I write this driver because I lost the paper ("manual") with
|
||||
* settings of jumpers on the card and I have to boot Linux with
|
||||
* Loadlin except LILO, cause I have to run the setupvic.exe program
|
||||
* already or I get disk errors (my test: rpm -Vf
|
||||
* /usr/X11R6/bin/XF86_SVGA - or any big file).
|
||||
* Some numbers from hdparm -t /dev/hda:
|
||||
* Timing buffer-cache reads: 32 MB in 3.02 seconds =10.60 MB/sec
|
||||
* Timing buffered disk reads: 16 MB in 5.52 seconds = 2.90 MB/sec
|
||||
* I have 4 Megs/s before, but I don't know why (maybe changes
|
||||
* in hdparm test).
|
||||
* After release of 0.1, I got some successful reports, so it might work.
|
||||
*
|
||||
* The main problem with OPTi is that some timings for master
|
||||
* and slave must be the same. For example, if you have master
|
||||
* PIO 3 and slave PIO 0, driver have to set some timings of
|
||||
* master for PIO 0. Second problem is that opti621_set_pio_mode
|
||||
* got only one drive to set, but have to set both drives.
|
||||
* This is solved in compute_pios. If you don't set
|
||||
* the second drive, compute_pios use ide_get_best_pio_mode
|
||||
* for autoselect mode (you can change it to PIO 0, if you want).
|
||||
* If you then set the second drive to another PIO, the old value
|
||||
* (automatically selected) will be overrided by yours.
|
||||
* There is a 25/33MHz switch in configuration
|
||||
* register, but driver is written for use at any frequency.
|
||||
*
|
||||
* Version 0.1, Nov 8, 1996
|
||||
* by Jaromir Koutek, for 2.1.8.
|
||||
* Initial version of driver.
|
||||
*
|
||||
* Version 0.2
|
||||
* Number 0.2 skipped.
|
||||
*
|
||||
* Version 0.3, Nov 29, 1997
|
||||
* by Mark Lord (probably), for 2.1.68
|
||||
* Updates for use with new IDE block driver.
|
||||
*
|
||||
* Version 0.4, Dec 14, 1997
|
||||
* by Jan Harkes
|
||||
* Fixed some errors and cleaned the code.
|
||||
*
|
||||
* Version 0.5, Jan 2, 1998
|
||||
* by Jaromir Koutek
|
||||
* Updates for use with (again) new IDE block driver.
|
||||
* Update of documentation.
|
||||
*
|
||||
* Version 0.6, Jan 2, 1999
|
||||
* by Jaromir Koutek
|
||||
* Reversed to version 0.3 of the driver, because
|
||||
* 0.5 doesn't work.
