Hi, I just got my fit-pc2i and I am trying to install gentoo on it, but I can't seem to get any livecd to recognize the hard drive, both the gentoo minimal CD and the Ubuntu 9.10 livecd's only see the internal flash, but not the HDD. The copy of Ubuntu that came on the hard drive seems to work alright with the internal hard drive.
Loading pata-sch only makes the flash drive available, not the HDD.

Re: fit-pc2i HDD on Linux
Thanks, it works fine with that patch.
Are there any plans to push this patch upstream to the vanilla kernel?

Re: fit-pc2i HDD on Linux
It will be fixed in the next HW revision of fitPC2i, it is not Linux kernel problem.
BTW slave disk detection works fine in Windows on current revision because of different detection procedure.

Re: fit-pc2i HDD on Linux
It's still a problem for people with the pilot run of fit-PC2i machines, so having the support in the vanilla kernel is still desirable (unless this can be fixed in BIOS?).
Would you have any objections to someone else sending this patch upstream?

Re: fit-pc2i HDD on Linux
No, we have no plans to send this patch upstream.
If you want to use some non-Ubuntu distribution - you will need to apply this patch manually and recompile the kernel. Our preinstalled Ubuntu has this patch.

Re: Issue with Linux installation on fit-PC2i
How can I apply this patch when booting on a live cd ex: Ubuntu Desktop 9.10?
Re: Issue with Linux installation on fit-PC2i
The thing is that dont really care about detection because we can mount the HDD in fstab and then do a mount /dev/sdb1 /media/hdd
Detection is needed with cd installation but we cant apply this patch
So this is useless for me. Still cant find any solution to install ubuntu server to HDD...

Re: fit-pc2i HDD on Linux
I am a bit confused about this answer. You say its a hardware problem that will be fixed in the next HW revision, yet windows can detect it correctly? How can it then be a hardware problem? And how can a patch on the linux kernel make it work?Denis wrote:It will be fixed in the next HW revision of fitPC2i, it is not Linux kernel problem.

I got a fit pc2i with this problem. I ordered the diskless, wanting to install debian on it using pxe. I am guessing I will need to deploy a different strategy now.
