Hi All,

I am a Newbe. I tried to install CRUX 2.4 on my laptop. During
installing and configuration, everything seemed to good. I was able to
install the core system to my SATA harddisk, furthermore my other
partitions were available as well.

Though when I completed install procedure, I tried to boot CRUX from
the harddisk, the boot process stopped with following messages:

"VFS: Cannot open root device "sda6" or unknown block (0,0)"
"Please append a correct "root=" boot option, here is the available
partitioins: 1600 4194302 hdc driver: ide cdrom"
"Kernel panic - not syncing: UFS: Unable to mount root fs on unknown
block (0,0)"

I am sure my fstab and boot loader config file is correct. Could it be
the problem that I did not use own lilo for CRUX in order to boot? I
edited an existed grub menu.lst of another linux distro that runs on
my laptop.

Any help is appreciated,

gellba

Hm, I don't know the error message, I think, you have installed grub into your
mbr (other wise this "root=..." stuff wouldn't appear), if not,

prt-get readme grub

will help you.

Afaik the grub shipped with the install iso will read it's configuration from
/boot/grub/grub.conf (but this will change, if you update grub, and reinstall it
in the mbr (see the previous grub email in this list)).

Hope this helps.

bye

Also make sure the sata driver and file system type are compiled into
the kernel (not modules).

Make sure SCSI target support, SCSI device support, SCSI disc support,
SCSI CD-Rom support and SCSI Generic support are built-in, as these are
required to create the device node and provide the SATA-SCSI interface.

Since Jaeger gave me a talking to over the inaccuracy of the above
statement, I'll point out that SCSI CD-Rom support, SCSI target support
and SCSI Generic support are not "required" if all you want is the
hard-disc.

But SCSI CD-Rom support is required in order to utilise a CD-Rom drive,
SCSI generic support is useful for card-readers and screwy CD burners
and SCSI target support I forget at the moment.

I edited the original grub file while installing crux, but after that
I was not able to boot crux for some reason. That's why I'll try some
other tricks like chainloading or re-write the mbr.

OK, I'll try pkgadd.

I've already altered grub config (see above).


Thanks
