Re: my kernel won't recognize ide drives
There is a problem I meet from time to time while trying to minimize the size of my kernel; using only the mainboard drivers fail without success. You also have to compile the generic ide drivers into the kernel.

So just in case, when booting and unsure which drive has what number, use the tab expansion in the grub interactive shell.

my kernel won't recognize ide drives - solved
You guys are generous and amazing. Thank you for the responses. I've been working on this issue for weeks, googling everywhere etc.. and the solution was so simple once I had help from the lfs community. I'm writing this so that maybe a future searcher might find it. here's my solution: I installed PCI Utilities-3.1.7 - http://www.linuxfromscratch.org/blfs/view/svn/general/pciutils.html the relevant part of the output of lspci was 00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA Controller [IDE mode] 00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller so in make menuconfig I enabled ati pata support option (device drivers/serial ata and parallel ata drivers/ati pata support) and Voila!!! ... fdisk -l the ide drive is sdb here's my original question: I recently built a system following the lfs 6.5 book exactly. The only difference in my distro is that I used kernel 2.6.30.10 instead of the suggested 2.6.30.2 kernel. In compiling the kernel I used all the default settings except the following: --I disabled loadable kernel modules --I added the drivers for my nic --I added limit and recent match support in the netfiltering section --I changed the processor family to athlon/duron The system harddrive is a sata and it all works perfectly. My problem is that I have a several pata (ide) drives that I'd like to add to the system. The kernel doesn't recognize them. fdisk -l shows only sda and in /dev the only harddrive listed is sda. I ran dmesg | grep hd and found no references to hdx drives. I ran dmesg | grep sd and found only a reference to sda. I took the kernel from a Knoppix installation (2.6.32.6) and booted my lfs system with it and all the drives including the pata (ide) drives now appear. This leads me to believe that my problem is with my kernel configuration. So the question is what kernel configuration changes do I have to make to get the kernel to recognize my ide drives? I realize that new kernels name ide drives sdx and that's fine. I don't need them to be labeled hdx. I simply want them to be recognized by the kernel. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

I realize that new kernels name ide drives sdx and that's fine. I don't need them to be labeled hdx. I simply want them to be recognized by the kernel. In menuconfig, device drivers, Serial ATA and Parallel ATA drivers - the PATA drivers start with 'ACPI firmware driver for PATA' and continue to the end of that section. Use lspci, and google, and the help for the driver options, to determine which is appropriate for the chipset(s) on your motherboard. This is probably a case where keeping the original kernel and modules is a good idea, just in case adding drivers means the existing sda becomes something else (which will play havoc with /etc/fstab). I recommend adding an EXTRAVERSION for the new kernel, and giving the bzimage a unique name (or 'an unique name' for some of the people here). If the new drives appear, but cause your existing drive to 'move', revert to the original kernel and then I would mount by label or by uuid (man fstab). As always, backups are a good idea, but with luck it will be a walk in the park. ĸen -- After tragedy, and farce, OMG poneys! -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
