Installing 4 IDE HDs in 1 PC (linux in the 3rd and 4th) Is this possible????

Post by Peter Berl » Tue, 10 Oct 1995 04:00:00



Hi:
        I am trying to install a total of 4 HD (not partitions) into a 486/33
using a pair of regular IDE controlers and 4 HDs. Is this possible?? In order
to achieve this I was thinking to disable everything (but HD support) on the
second controler and at the same time enable it as a secondary controler. Will
this work?

        The idea is to have Linux installed in the 3rd and  4th HD.    

        Any ideas/suggestions/comments are more than very welcome.

        Many tx in advance

You may have problems with the interrupt line, unless you can
configure the second controller to use irq 15. I'd suggest buying a
single controller card with dual IDE or EIDE channels.

I'm running 3 drivers from a local bus EIDE controller, 2 EIDE drivers
(1 connor, 1 WD), and 1 IDE drive (WD). Works fine. The first channel
has the 2 WD's on irq 14, and the second channel has the connor on irq
15.  Didn't require a special kernel driver for Linux 1.2.8.

Steve.

 think I can handle changing my intrupts on my controllers, but these are
both not EIDE controllers.  My BIOS will not recignise more then 2 hard
drives, how do I tell Linux that they exist?  

(If somneone knows the answer for OS/2 as well that would be good, I will pro
bolly run OS/2 on some partition)

No need to.  Linux will find them.
