Yes, make sure that it is indeed pointing to the correct drive.8-) -- |

This is the relevant part of my grub.conf title Gentoo kernel-2.6.22-r9 root (hd0,0) kernel /boot/kernel-2.6.22-r9 root=/dev/sdb3 vga=0x31B video=vesafb:mtrr:3,ywrap,1280x1024-32
I have 2 SATA disks, the one on the first channel has Windows, the one on the second has Gentoo. Go figure why I had to put (hd0,0) in it, but my box kept non-booting until I changed that from (hd1,0) to (hd0,0) [edit] Quote:

Either way that's not preventing your booting process, it's auto BTW

There hasn't actually been a whole lot of compiling thus far... The little bit there has been was fast and pretty. I made the following changes to /boot/grub/grub.conf and reinstalled grub.
Note: Emphasis on (hd0,0). I actually added both options for me to test each and the first partition on (hd0) began to successfully boot Linux. Note that I haven't actually attempted to boot my Windows system from this grub install, but I assume it is correct. From the livecd (hd1) was correct so I stuck with those values when installing grub. Perhaps when booting my slave drive the BIOS switches them or something... Unfortunately, booting my kernel didn't get too far and eventually the kernel panicked. I'm going to have to recompile the kernel. Hopefully I do it correctly this time... So how do I determine which modules to build into the kernel and which ones to build as external modules? Should I just go through the entire make menuconfig checking out the help section for each node and guessing? -- acc.js | al4anim - Allegro 4 Animation library | Allegro 5 VS/NuGet Guide | Allegro.cc Mockup | Allegro.cc <code> Tag | Allegro 4 Timer Example (w/ Semaphores) | Allegro 5 "Winpkg" (MSVC readme) | Bambot | Blog | C++ STL Container Flowchart | Castopulence Software | Check Return Values | Derail? | Is This A Discussion?

The easiest way to do it would probably be to go through every menu option and turn all compiled-in modules into external modules. Then, go through and find the options necessary for you to boot, and set those to be compiled-in. What message did the kernel give you? -- Ryan Patterson - <http://cgamesplay.com/> |

the panic may not be module related. First I'd make sure the "root=/dev/hdb3" is correct. and try and post the message you get when the kernel panics. -- |

See if your SATA controller is in raid mode, and turn it off. Try "enhanced" and "compatibility" mode, the latter will make the sata disk appear in the spot the first pata disk usually is. -- |

I have the same SATA controller. Verify that "Intel PIIX/ICH SATA support" is compiled in. You can find it in Device Drivers -> Serial ATA (prod) and Parallel ATA (experimental) drivers (kernel source 2.6.19-gentoo-r5). -- Ryan Patterson - <http://cgamesplay.com/> |

I wouldn't go changing your RAID settings at this point, or it's going to fuck with your Windows install. At this point, I assume you had to install Windows with a RAID driver. Turning off RAID will likely make windows throw a blue screen pretty quickly on boot. Just make sure you have the right drivers compiled IN to your kernel for the controller, and if anything is required for LVM to work, make sure that is compiled in as well. Remember, unless you mess around with initrd's and stuff, your kernel needs to be able to access your drives without loading any modules. |

My servers run off LVM and/or MD raid (root as well), and they are all enabled as modules. Thats the joy of initramfs, you just generate a new one, and wham, all the modules you need are loaded before linux even attempts to init the real root filesystem. -- |

Going with stage1 will only mean you'll need to compile GCC, glibc, stdlibc++-v3, binutils and a few other packages. It doesn't take all that much time, actually. Though I haven't used the official handbook for ages, I usually just get some of the "experimental" guides from Gentoo forum. They mostly go with stage3 base but compile toolchain anyway to make sure that system is as stable as possible. When making the first Gentoo install I wouldn't bother with anythinb tut stage 3. Get something to work and work on from there. __________ |

VFS: Cannot open root device "sdb3" or unknown-block(2,0)
It is as I feared. Your kernel is compiled with the IDE modules...NOT your SATA modules.::) Also, are you using hd0,1 or hd1,0 for the root in your /boot/grub/grub.conf file? root (hd1,0) //really /dev/sdb1, partition 1. // If you installed boot on your third partition... use root (hd1,2) (3-1=2) kernel /vmlinuz-2.6.22-gentoo-r2 root=/dev/sdb3 //set root= to your actual / directory You can also use the new style ATA modules for your IDE CDROM drives as well...they would become: /dev/sr0 and /dev/sr1. I believe that the major push is towards this anyway, as quite a few distros are doing this. You may experience problems running both subsystems (the new style ATA and the old style). Also, make sure you compiled in support for the filesystem you are using. If you did not compile in support for reiserfs and you are using reiserfs as your filesystem...well, no wonder it doesn't work!::) I believe there have been a couple of people here that said they had that same chipset. Just find those in your kernel's menuconfig and make sure they are being compiled in.::) Quote: Not to fight you, but: device.map (fd0) /dev/fd0 Actually, you can change that file to say whatever you want after...but if you don't do the grub setup again...it does not take effect!:P -- |

Thanks. I'll check it out when I get home. Does anybody have an explanation for why grub would interpret them that way?
