I ran in to two problems while installing 64studio x86 on my Pentium 4 2ghz with Delta 44 sound card. Problem: I had an existing Debian installation on the 1st partition, swap on the second and installed 64studio to the third. After the install to a second third partition finished, I rebooted and got grub error 21. Solution: Booted up in rescue mode, copied the vmlinuz-2.6... from the third partition /dev/hda3 to the first /dev/hda1. Modified grub to point to the first partition to get the vmlinuz file, but set root=/dev/hda3 (the partion with the 64studio install). Trying to recall from memory it looked something like this: root (hd0,0) kernel /boot/vmlinuz-2.6.something root=/dev/hda3 ro quiet initrd (hd0,2)/boot/initrd.img-2.6.something Problem: I can play audio out of my Delta 44 but can't get anything in for recording. Solution: Open up the envy24 mixer and raise the level of the ADC slider. Now I get audio in.

I was looking for a place to post this, may as well add it on here. I replaced two SATA data drives with a single larger SATA data drive recently. the OS is on IDE drive. I put the new drive in an external enclosure temporarily, and booted to a Sidux live CD (because it gave me usable Nvidia video without juggling drivers). I ran gparted to create partitions and format the new disk, then did something like: cp -R /old/disk /new/disk (make sure both disks are mounted properly) When that was done, I edited the ORIGINAL /etc/fstab to reflect the drive change (mostly just commenting out the missing drive). Be sure that you are editing the one on the original OS drive. If you just edit /etc/fstab you will be looking at the one that exists in RAM for the liveCD. The one you want is something like /media/hda1/etc/fstab (some Linux variants will use /media/sda1. I'm at work and can't look at my 64studio install right now). Powered off, physically moved the drives around, and was suprised to see Grub: error 15. Error 15 is basically a "file not found" type of message. I had only changed the /etc/fstab to reflect the new drive, and had not changed anything else. After looking in my BIOS, I found that my boot order had been changed, pointing to a SATA drive instead of the IDE drive. Changed it around, and it came back up fine. I was/am puzzled about if it was pointing to the wrong drive, how it could get a Grub error at all. It seems like it should have been an error like "no operating system found".
