YDL 2.3 iMac Rev A - can't boot

[yellowdog-newbie@lists.terrasoftsolutions.com]

Hi,

I have an iMac Rev A (233 mhz) and I've tried four times to install YDL 2.3 without 
sucess. 

I followed guidelines: 2 partitions (1 unallocated for YDL - 2nd HFS for Mac OS 9), 
installed OS 9 in second partition, then installed YDL (made 3 partition: 10 MB Boot, 256 
MB Swap and the rest for Linux - 20 GB). But after restart I only get a gray screen. The 
install was in text mode.

Then tried reverse sequence: installing Mac OS 9.1 in first partition (not HFS Extended) 
and YDL 2.3 in second partition (made 3 partition: 10 MB Boot, 256 MB Swap and the 
rest for Linux - 20 GB). Installation went fine. After restart I get the text menu to choose 
which to boot: Mac OS, Linux or CD. Selecting any of them only gets message like 
"please wait, loading...." and just freeze.

So finally I decided to install just the YDL. Initialized HD with 1 partition "Unallocated", 
restart YDL CD, follow instruction (10 MB boot, 256 MB Swap, 20 GB Linux). Installation 
finish without error. Now, after restart I get the following:

boot: linux
Please wait, loading kernel....
/pci/mac-io/de@20000/disk@0:8,/boot/vmlinux: Input/output error

I've searching through the messages in this group, but I didn't found what to do to resolve 
the problem.  

I would like to hear from whoever is in this list who has susscesfully installed YDL 2.3 in a 
iMac Rev A. 

Thanks in advance
