e-ide driver 6.30 uses same interrupt on IDE-0 and IDE-1

e-ide driver 6.30 uses same interrupt on IDE-0 and IDE-1

Post by Sebastia Altem » Tue, 04 Sep 2001 19:02:32



I have a 10 GB SeaGate disk that works fine under Windows 95, not with Linux.

With W95, the Control Panel + Device Drivers + Hard Disk controllers says
it is using "standard double driver PCI-IDE", and its resources are

   I/O address --- 1F0-1F7 --- 170-177
   IRQ         ---      14 ---      15

With Linux, when Caldera eDesktop 2.4 starts, it logs

  Uniform multi-platform e-ide driver revision 6.30
    IDE-0 at 0x1F0-0x1F7 on IRQ 14.
    IDE-1 at 0x170-0x177 on IRQ 14.

I guess that "IRQ 14" ( two times ) makes this disk to be not reachable
( any access to this disk ends up with "lost interrupt" ).

How can I tell that "e-ide" driver to use IRQ 15 on IDE-1 ?

Thanks a lot. Sebastian.

 
 
 

1. e-ide driver 6.30 uses same interrupt on IDE-0 and IDE-1

I have a 10 GB SeaGate disk that works fine under Windows 95, not with Linux.
It is connected, alone, on secondary IDE (hc).

With W95, the Control Panel + Device Drivers + Hard Disk controllers says
it is using "standard double driver PCI-IDE", and its resources are

   I/O address --- 1F0-1F7, 3F6 --- 170-177, 376
   IRQ         ---      14      ---      15

With Linux, when Caldera eDesktop 2.4 starts, it logs

  Uniform multi-platform e-ide driver revision 6.30
    IDE-0 at 0x1F0-0x1F7 on IRQ 14.
    IDE-1 at 0x170-0x177 on IRQ 14.

And then few

  hdc: lost interrupt

I guess that "IRQ 14" ( two times ) makes this disk to be not reachable

How can I tell that "e-ide" driver to use IRQ 15 on IDE-1 ?
I have tried ( in LILO.CONF )

    append = "ide1=170,376,15"

but starting Linux logs this :

  ide1: ports already in use, skipping probe
  ide2 170-177.376, IRQ 14
  hde: lost interrupt

and ide1 goes invisible.

Thanks a lot. Sebastian.
