I don't quite understand it, since I thought hda was for scsi and this is an ols laptop which uses IDE. Other way around. Traditionally, 'hd' was for IDE and 'sd' was for SCSI, though under a modern kernel, pretty much everything should be using 'sd'. That includes USB devices, SATA, and these days, most IDE drives too. If your LFS kernel is using 'hd' but Fedora uses 'sd', you're probably *not* using the same drivers. You're using the older one (under the ATA/IDE section in the kernel configuration), and they're using the newer one (under SATA/PATA), or something like that). Both may work, but the former are considered obsolete.

[lfs-support] Cannot open root device sda1
I am using LFS 7.0. I have completed everything just trying to boot the system. When I do boot,it panics and I get: Cannot open root device sda1 or unknown=block(2,0) ... hda1 hda2 hda3 hda4 My grub.cfg looks just like the one in the book. On the same machine, I booted into Fedora, which was using a 2.6 kernel and used lspci to see which drivers I needed, and included those. I did build the grub cd so I can boot from that and try different approaches. I am trying to figure out if I am missing a driver, or I have grub.cfg misconfigured. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Re: [lfs-support] Cannot open root device sda1
Maybe it's called sdb1 or hda1 or perhaps you compiled your kernel with modules? I considered hba1, but never changed it since when I boot into Fedora, I always mounted it as /dev/sda1. Anyway that got me beyond that panic, but now its complaining about fs ext3. At this point should my fstab be using /dev/hda instead of /dev/sda I set up? Or is it complaining about not recognizing the filesystem type of ext3? Thank you. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

hd* has always been used for IDE if i remember correctly.
