need help detecting my second hd.

inha · n00b Joined: 05 Sep 2004 Posts: 35

It's connected to a promise tx2 ultra100 ultra ata/100 controller card. I originally forgot to add support for it when I configured my kernel which I managed to fix on my own. now the system seems to detect the card but it still doesn't detect the hd.

lspci gives me this:
0000:02:01.0 Unknown mass storage controller: Promise Technology, Inc. PDC20268 (Ultra100 TX2) (rev 02)

there's only hda(the hd) and hdc(dvd drive) in /dev. also there is only host0 in /dev/ide and there's supposed to be a second host in there.

any ideas? all help is appreciated. I tried searching the forums (read fora if you're a spelling nazi) but couldn't find an answer that would help my particular problem.

When your PC is booting ( should be one of the first messages )

Check what has been detected as IDE stuff. If the BIOS does not detect your hardware linux wont !?!

But Im not sure if this applyies for an Card that you plug into your motherbord. Im not used to this. If that is the case !

And check your cables and jumpers on your hard drives !

maybe I should have been more specific. I have fedora core 2 on my second hd and it detects the card and the hd and I can mount my gentoo partitions on fedora but it doesn't work the other way around.

have you compiled any specific drivers into your kernel to support the promise card? you probably need to.

also, it doesnt matter if the bios detects your drives or not - linux does its own probing for disks.

I did compile the drivers into the kernel.
lspci gives me this: 0000:02:01.0 Unknown mass storage controller: Promise Technology, Inc. PDC20268 (Ultra100 TX2) (rev 02)

but it doesn't come up on dmesg | grep pci, for which I can't think of an explanation.

please post the "0000:02:01.0" line of "lspci -n", and say which driver you included into the kernel to try and support this.

here's the line: 0000:02:01.0 Class 0180: 105a:4d68 (rev 02)
and this is the driver: PROMISE PDC202{46|62|65|67} support

one more thing: could this be becuse linux searches for the drives before it searches for the pci devices? in the startup the harddrive checks seem to be before pci hotplugging support is enabled. or am I just talking out of my ass?

is CONFIG_BLK_DEV_OFFBOARD enabled?

under drivers, ATA/ATAPI/MFM/RLL support, make sure this is checked:
[*] Boot off-board chipsets first support

I compiled the kernel again and installed it the same way as in the handbook but my system is still not detecting the hd.

boot up fedora, see what modules are loaded, then build those modules and load then in gentoo.

none of the modules modprobe -l found seem to be in any way related to ide drives or the promise card. the kernel settings seem to be identical on the relevant parts.

I think I'm going install gentoo again some day soon. Maybe I'll pick up where I went wrong then and I have a better understanding of use flags and the process in general now so maybe I could get a better system done anyway.

just from looking at the naming i can tell you are using the wrong driver

I can't believe I didn't notice that. Thanks. I'll give it a shot once more.
