I'm relatively new to Linux (only having been running it for a year or so,
and having been a serious BSD head before hand) so please excuse any
potentially dumb questions that follow :)
I have recently bought a Promise FastTrak 100 IDE RAID controller and 2 x
IBM Deskstar 76.8Gb IDE disks to connect to it (striped, with a view to
adding 2 as mirrors when I have some more cash)
I've been running the 2.3.99 and 2.4 test kernels for a while, and after
testing / installing the Promise standard (non RAID) ATA100 controller with
one of the Deskstars, I decided to take the plunge and upgrade to the RAID
controller and multiple drives.
Now with the standard IDE/100 controller (using the PDC20267 chipset)
everything works a treat ... however having swapped this for the RAID
version I get the following at boot time (using an ABit BP6 mobo with dual
533 celery's)
PDC20267: IDE controller on PCI bus 00 dev 78
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: ROM enabled at 0xe9000000
PDC20267: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER
Mode.
PDC20267: neither IDE port enabled (BIOS)
I've tried removing any and every card that's in there, save the AGP TNT2
card ...
I've tried disabling the on board IDE controllers (to free some more irqs),
but had trouble getting my root disk to boot using the on board HPT366
controller, so this part of my test is inconclusive, however as the PDC20267
based controller worked before, I'm a tad confused.
Is it IRQ based (I've seen some mention of this in the archives that I've
searched), or do I need to do something else?
I'm about ready to start hacking drivers/ide/ide-pci.c to see if I can make
things work, but though I'd ask here before I start rewriting parts of a
kernel I don't know that much about :)
Any help gratefully received!
(additional info just in case it helps ...)
