Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have motherboard Asus P5E3 with 6 SATA ports:
/dev/sda: member of ICH9 RAID5
/dev/sdb: member of ICH9 RAID5
/dev/sdc: *TARGET DRIVE* for installation (SINGLE, not member of RAID)
/dev/sdd: member of ICH9 RAID5
/dev/sde: DVD ROM (Source)
cfdisk without parameters say error. When I run "cfdisk /dev/sdc", I can manage partitions, add target partition and partition for swap... But then when I run "setup"... it could not find created partitions
RAID5 contains critical data, so disconnecting /dev/sda and /dev/sdb simultaneously or reordering drives (sda <--> sdc) may be dangerous... //There is an option in BIOS in AHCI mode to software switch off SATA ports, but it seems it affects only BIOS
Is there any way to point setup to /dev/sdc immediately?
There was one strange thing:
if I use cfdisk, everything is OK,
but if I use fdisk (partitions type 82 and 83 are already created, I just enter 'p' and then 'w' commands), it always says that the partitions are written but could not be read again, and the changes will affect to setup after system restart.
Yes I did and partitions are accessible for kernel so it's trouble with setup program only.
It's surprising that Slackware setup contains rather poor help.
There is the paragraph about activating swap before run setup (mkswap, swapon) - swap is activating with no errors, but ADDSWAP still could not find it (I think because setup firstly try access /dev/sda and fail).
So /dev/sda,sdb broken, how to install to /dev/sdc?
So, I have ICH9 RAID, BUT I DO NOT WANT TO USE IT WITH SLACKWARE. I also don't want to migrate or backup it somewhere or reconfigure because it contains critical data. I need to install Slackware to /dev/sdc that is a single hard drive, not a member of RAID5 (but /dev/sda,sdb and sdd are members).
1) cfdisk without parameters say error: partition ends after the end of disk or something like (it's about /dev/sda as default);
2) setup program could not find partitions with type 82 and 83 prepeared with `cfdisk /dev/sdc': /dev/sdc5 and /dev/sdc6 (setup is also scan firstly /dev/sda and I need a way to prevent it).
I need a way to tell setup program to use /dev/sdc immediately, without making scan that in always fails due to unsupport intel matrix storage by kernel.
unSpawn, thank you.
H_TeXMeX_H, I tried, but problem partitions are still visible Anyway also thanx a lot. I've just started to explore setup scripts in Slackware
# which setup
This is a script, not a binary. It calls /sbin/probe at first that is also a script. probe contain at the begin:
# This is 'probe', a wrapper for using fdisk to gather drive info for
# the Slackware setup scripts...
probe says 'Unable to seek on /dev/sda' and exit. That is the problem. It's here.
Analyzing script, I found that /sbin/probe use /proc/partitions that contain information about absolutely all partitions:
and delete lines from 3 (minor 0) up to first inclustion of sdc... But 'w' command (in ed text editor) fail with: ""/proc/partitions", /proc/partitions: Input/output error". I still have no rights to write.
No, H_TeXMeX_H, that was temporary installation environment, I think that way is more simple than to totally rewrite probe and setup scripts
It was successfully installed... but I can't do normal boot, only single user mode... of course "due to disk errors"
No kernel patch for matrix storage, no way to skip checking sda/sdb at the time of boot (?)... Don't know what to do.
Making fake raid - it was my big mistake. It's nowhere to migrate raid this time... They say ubuntu and freebsd have no such problem, maybe I'll try, but these are not the soft I want try)
