- Hello there,
- I have been with Linux for the past 10 months and really never had any
- problems , except some minor ones that I was able to solve myself ,
- with the help of the articles posted in the newsgroup.
- So now , I think it is time to post ...
-
- Here is my problem :
-
- I have a 486-50 , ET4000
- Multi-IO controller 2Serial , 1Parallel , IDE , FLOPPY
- I 'inherited' recently a 16bit (WD1003-MM2) AT HD Controller and
- a ST-251-1 Hard disk , which I would like to put working.
- From the past articles refering to MFMs+IDEs , XT disks , etc,
- I got the impression that :
-
- If you have the IDE controller set as the primary one and also
- set the type of drive in the CMOS ,
- change the WD controller to use the secontary address (170H)
- put 0 or NO-HARD-DISK in the CMOS for the second disk
-
- THEN the only thing you need , is just a driver to access the
- second controller through the ports at 170H..173H
-
- Right .... I found a Shareware program called 3_DRIVES (somewhere
- in the dskutl directory in simtel20) and checked if the HARD DISK
- was working ....
- Success... I know can have access to the disk but only through DOS.
- I can even make it a stacker drive and use it for storage...
- But what about Linux ?
- It should not be very difficult to implement a driver like the SCSI
- ones and add it to the Kernel ...
- Really , the main information about registers and ports is there ...
- You only need to add support for the secondary addresses ...
- I also took a look in xt_disk driver , but the registers are quite
- different between XT and AT type controllers (????)
- And since I am not a C guru ,
-
- ANY HELP WELCOME ...
- (Maybe Pat , the guy that has written the code for the xt_disk driver
- could mail me , or post to the group ???)
-
- Thanks in advance ...
