Well I think the problem is that during uncompression I get this message.

root@deinst01> gzip -d initrd.gz

gzip: initrd.gz: decompression OK, trailing garbage ignored

when I recompress this file it is smaller than the original and doesn't boot anymore.

What is that "trailing garbage ignored"?

That should work, but you need to gzip -9c because otherwise the initrd can't be uncompressed.

Hello List,

I need to update the content of the 5mb initrd file that resides on the tftpserver. gunziping, mounting minix fs changing it and gzipping it doesn't do the trick.

How does suse/novell create this file?

Thanks in advance

It's possible to append a custom DSDT to the initrd. DSDT is a BIOS ACPI table which is often buggy on laptops and can be replaced. But for non laptops that's rarely done and the installer never does it on its own. -Andi

Hi Andi, this initrd is right off the SLES 8 SP3 cd. Without the trailing garbage it doesn't boot anymore. How can I re-add this to the initrd?

The trailing garbage message can be ignored. I have no idea where it comes from, but after recreating the initrd as described earlier, it works. What exactly did you change in the initrd? Anas Thomas Mieslinger wrote:

I'd like to install a new ibm x336 with bcm5721 network chips. These are not support by the standard kernel so I need to change the bcm5700.o. -- GLS IT Services Thomas Mieslinger GLS Germany Str. 1-7 fon: +49 6677 17 463 36286 Neuenstein fax: +49 6677 17 111 Germany eMail: thomas.mieslinger@gls-itservices.com Anas Nashif schrieb am 25.11.2004 21:22:33:

Hello List, I made a mistake and used a smp Kernel with the initrd from the bootcd. Now it works fine.

Probably one or more appended bootsplash images, or other appended info. See the mkinitrd script for details on appending info (source code). Cheers, Leen
