Robert,
You need make sure the kernel versions in your boot image and your netstg1.img are the same.
mkdir /mnt/stg1
mount -o loop netstg1.img /mnt/stg1
cp /mnt/stg1/modules/modules.cgz
gunzip modules.cgz -S .cgz
cpio -ivdF modules
Check that the version in there matches the version in your boot(net) image... If not - update it... Obtain the correct kernel-BOOT rpm, create a new directory for that version, copy any additional
drivers in, gzip/cpio the modules back up and drop it back into your netstg1.img
I wrote the below enclosed script to ease the cracking open and buttoning up process: Simply type:
bootcrack bootnet.img
The script simply opens the img file, opens the initrd file inside that, and optionally opens the modules/modules.cgz (use the -m option) into a temp area (configurable using ~/.bootcrackrc file).
Once the img is cracked open you can manipulate the kernel vers, etc... then... simply use the finish.sh script that bootcrack places in the top level temp directory where the image has been cracked
open. The finish.sh script will button everything up.
The script is alpha - let me know if you have suggestions for improvement.
Let me know how you make out...
Best of luck!
Mike

Subject: Second stage does not match boot disk error
I am attempting to build a RedHat AS 2.1 Update 2 (2.4.9-e.24) boot.iso disk with the 1.18k megaraid driver included in it to install on many Dell PE 1750s with the Perc 4/Di RAID cards. I know there
are some driver disks available for the megaraid driver, but driver disks just add too much complexity for the sometimes non-technical staff that has to do the final install of these servers.
Whenever I use my new boot disk, I get the following error message:
"The second stage of the install which you have selected does not match the boot disk which you are using. I am going to reboot your system now."
Does anyone have any idea where this is coming from? Or how Anaconda determines a match between boot and 2nd stage media? It seems to come shortly after the netstg1.img file is downloaded to the 1750
being built.
(virtual console output at the end of this message).
Here is the long version of what I've done to build the new images:
- download the megaraid drivers (1.18k) and compile against 2.4.9-e.24BOOT using DKMS per linux.dell.com.
-Using the basic procedure outlined at
http://www.puschitz.com/Kickstart.shtml I added the following to isolinux/initrd.img, RedHat/base/stage2.img, RedHat/base/netstg1.img:
- added new megaraid.o to modules.cgz
- added the following line to the pcitable:
0x1028 0x000f "megaraid" "Dell|PowerEdge Expandable RAID
Controller 4/Di"
Sorry for the long email, but here's the console output when I get this
message:
* transferring
