Greetings.
I've been trying to get the KM R5C7 installation to work and have had just a hoot of a time. System is an
Athlon 64 3400
2 Hauppauge 350's
1GB RAM
nVidia GeForce 6300 (this is used for the display)
300GB SATA drive for HDD
DVD burner on IDE0.

I've wiped the /dev/sda drive with Safedisk (to purge the MBR) and ensure a clean disc.

What I've done
Boot KM R5C7 (no switches)
Select Manual Install
(2 item menu displays)
Select Partition
Create 4 Partitions (I know /cache is no longer needed after searching for more help, but this is what I've done so far).
/dev/sda1=/ (2560MB)
/dev/sda2=swap (1536MB)
/dev/sda3=/cache (10240MB)
/dev/sda4=/myth (everything else)
Write to drive and exit
Switch to console2 (ctrl-alt-f2)
mkswap /dev/sda2 && swapon /dev/sda2
mke2fs -O super_sparse -m0 -i8000000 -L cache -M /cache /dev/sda3
mke2fs -j -O super_sparse -m0 -i8000000 -L myth -M /myth /dev/sda4
Switch back to console1
All six options are shown
Load the /KNOPPIX/knoppmyth-sata config
Config installation
Set TZ and Time
Set user (not mythtv) and passwd
Set Admin passwd
Select installation partition (/dev/sda1)
Select boot to MBR
Accept settings and watch install (looks to proceed fine).
When I OK the install, I'm dropped to prompt.
type reboot and hit enter
Remove the disc from tray
Watch the restart show LILO (text only)
Watch "Invalid Partition" messages like it can't find the boot image stream for a moment and then it stops.

From here, I've tried several things...booting from Knoppix disc, mount -rw /dev/sda1 to see if I can edit /etc/lilo.conf and then run lilo, but I get lilo errors. Try to chroot /mnt/sda1 and retry lilo and can't write to /dev/sda1.

Help...I'm just dying to get this sucker working, and I LOATHE the idea of MCE being run on this pretty thang. I've run Gentoo on here and the hardware just screams, so I know it's not a h/w issue.

TIA.

Based on information from the forums, I tried again.
3 Partitions this time:
    /dev/sda1=/ (20480MB)
    /dev/sda2=swap (1536BM)
    /dev/sda3=/myth (everything else)

Wrote partition w/o any problems and installed KM with same settings (MBR and /dev/sda1 for installtion).
After install appears to succeed, I followed the process to insert the sata_nv.ko module into initrd
    mount -rw /dev/sda
    cd /mnt/sda1/boot
    gunzip initrd
    mkdir /mnt/initrd
    mount -o loop initrd /mnt/initrd
    cp /mnt/sda1/lib/modules/2.6*/kernel/drivers/scsi/sata_nv.ko /mnt/initrd/modules
    (I checked and the sata_nv.ko is what KM is using to install)
    vi /mnt/initrd/linuxrc
    and added "insmod /modules/sata_nv.ko" just before the mount for sda1
    saved the change
    cd /mnt/sda1/boot
    umount /mnt/initrd
    gzip initrd



So, I then chroot /mnt/sda1 successfully,
but when I
lilo -v
I get

Reading boot sector from /dev/sda
Fatal: open /dev/sda: Permission denied.


Of course, all this so far hasn't let me boot after install yet.

So, what am I missing? Any help is appreciated.

TIA.

Hey all,

I was having the same issues with an MSI K8N (Neo 2 Platinum) and a 320gb Seagate SATA. :(

The first problem I was having was that my one and only SATA drive was showing up as /dev/sdb instead of /dev/sda. :shock:

After fiddling with BIOS and cable connetions and not seeing why it wasn't showing up as sda, I read that USB devices can sometimes bump a SATA drive from sda to sdb. Lo and behold but after disconneting all the USB peripherals except my wireless keyboard, the drive finally started to show up as /dev/sda!

Secondly, because my motherboard uses an nVidia chipset (nForce 3), I tried the steps outlined by nybbler in this useful SATA initd thread

This got me up and running for the first time! Now I am off to configure Myth. Good luck to everyone attempting SATA! I hope that the SATA issues get worked out for future releases of KM, because it really is a fantastic project.

Hi,
I have done a couple sata drives and getting lilo to run clean is tricky sometimes.

referring to post :
Quote:
mount -rw /dev/sda1 to see if I can edit /etc/lilo.conf and then run lilo, but I get lilo errors

try
mount -o rw,dev /dev/sda1 /mnt/sda1
chroot /mnt/sda1
nano /etc/lilo.conf
lilo -v there is a comment about backup if I recall correctly
ctl d

I built one using external usb (ide box so usb was sda1) then after, installed the drive in a sata box and finished the first boot up.

The next release should hopfully address this...

Just to update everyone, I figured this one out finally by piecing together info from several forum posts scattered about.

I performed the 3-partition Manual Install. After it completes, I (not sure if I rebooted and used KM for rescue disc or no, but here's what I did after my 2nd posting up there):
    Rebooted KM disc and quit the installer (used it as a rescue disc)
    mount -rw /dev/sda1
    vi /mnt/sda1/etc/lilo.conf

    Removed the offending line (shift-DD) from the LILO.CONF (the "Please Remove...") from ~line 3ish
    :wq
    chroot /mnt/sda1
    lilo -v
    reboot


and I FINALLY got to the X and KM configurations!

Thanks to all the posters who helped. I will try to get the entire sequence written out and posted to the Wiki this weekend (no promises!) for those who could use a single/complete run-through of this.

Thanks,
K
