I just got PCI IDE controller and have troubles making it work with
linux (2.4.18).
the docs in linux/Documentation/ide.txt say that linux will probe for
ide devices that have device files in /dev or that I can force it to
probe using ide2=0x1e8,0x3ee,11 (kernel option). So I thought it should
almost work by itself but it doesn't. Here's what I did:
in /etc/lilo.conf, I tried these (and some other) variations:
append = "ide2=0x1e8,0x3ee,11 ide3=0x168,0x36e,11 hdg=cdrom"
append = "ide2=0x1e8,0x3ee,11 ide3=0x168,0x36e"
append = "ide2=0x1e8,0x3ee ide3=0x168,0x36e"
I also tried it without append and it wasn't recognized at all (ide2,
ide3 wasn't mentioned anywhere during boot and it, of course, didn't
work either).
ide.txt says that the above addresses usually work but the PCI
controller setup (I can enter during boot) shows different addresses,
those are also listed in /proc/ioports:
cc00-cc07 : Artop Electronic Corp ATP865
d000-d003 : Artop Electronic Corp ATP865
d400-d407 : Artop Electronic Corp ATP865
d800-d803 : Artop Electronic Corp ATP865
dc00-dc0f : Artop Electronic Corp ATP865
should I use these in kernel line? which ones?
the output during boot shows that the kernel options are used:
Kernel command line: auto BOOT_IMAGE=linux ro root=304
ide2=0x1e8,0x3ee,11 ide3=
0x168,0x36e,11 hdg=cdrom
ide_setup: ide2=0x1e8,0x3ee,11
ide_setup: ide3=0x168,0x36e,11
ide_setup: hdg=cdrom
but the ide2 and 3 do not work:

idebus=xx

hdb: [PTBL] [4982/255/63] hdb1 < hdb5 hdb6 hdb7 > hdb2
I thought that the problem might be shared interrupt (11 is also used
by usb ports) but it doesn't work even when I disable USB in BIOS setup.
When I connect everything to PCI controller and disable the ide on
motherboard the computer starts booting, the disks show just like they
should (hda, hdb for HD, hdc for cdrom), the lilo boots kernel but for
some reason kernel doesn't want to mount root file system, it's excuse
being that root device 304 was not found... what does that mean? I
thought that as long as it's on the same ide (ide0) and same position
(master) it shoudl work.
another confusing thing is that the pci ide controller is listed as
follows in lspci:
00:09.0 SCSI storage controller: Artop Electronic Corp: Unknown device
0009 (rev 02)
what could that mean?
the motherboard is using VIA chipset, here's the full output of lspci:

any ideas on how to make it work? TIA!
