Do both OSX AND YDL need to be in 8GB for old Macs?

I think the problem will come when you try to boot OS X from yaboot.  
Yaboot uses Open Firmware and it will only boot partitions in the first 
8 GB of the disk on Old macs like the first generation iMac and beige 
G3's.
Here is what my partition map looks like:
/dev/hda 1-6 apple partition map and drivers
/dev/hda7  apple_bootstrap 1MB
/dev/hda8  Mac OS X 6 GB
/dev/hda9  YDL root / 1.5 GB
/dev/hda10 swap 512 MB
/dev/hda11 /usr  4GB
/dev/hda12 /home 4GB
/dev/hda13 /var 1GB      If you are going to be compiling a lot of 
programs or running a lot of servers I would make this if not don't 
bother just leave it in root
/dev/hda14 Mas OS X extras and applications  80GB

If you set up like this you will find that you will only have about 
500-750 MB in the root partition and the majority of the install will 
be in /usr which is where all of the programs go.  If you ever want to 
boot directly into OS 9 then you should also make a seperate partition 
for it in the first 8GB and decrease the OS X partition slightly.  You 
can probably get by with 500 MB or less for an OS 9 partition and then 
put your applications on the extra space you have for Mac OS X extras.

Hope this helps some.

Surely OSX doesn't also need to be in the first 8GB (as putting
OSX+extras AND a YDL workstation install all into the first 8Gb would
be a bit of a cram)?


The fact that the OSX alone runs fine suggests it is Ok where it is.
has anyone else successfully installed YDL plus OSX on a rev 1 G3 B&W
wih OSX in a partition beyond the first 8GB?


Many thanks.
