install problem

Hi All,

 I unsuccessful tried install SuSE from CDs on my Sparc Station5.
I tried 3 methods with some variations:

1. Classic
 YaST stoped before installing of packages with some error like
"instert CD1"  When I checked box "show detais" it said that can't
mount CD1 becuse of /dev/sr0 is already mounted on /var/adm/mount ...
 I switched on shell and saw that yast run from CD. Not from some
ramdisk. Of cousre fuser show that /dev/sr0 is under kernel so I can't
kill it ;-)

2. From HD
 Than I tried to copy 1st CD contents (except k2de* & x*) on free
partition on /dev/sda5.
 After boot from CD and run install from hardisk YaST asked on which
partition and which directory install source is...
I've tried all posible directories from "/" to "/sue/inst-sys/" but
yast can't found nothing from which install.

3. YaST from HD
 Boot into rescue mode, chroot to /suse/inst-sys (on /dev/sda5) and
run /sbin/inst_setup or something of /usr/lib/YaST2/bin/ have not
successed too. The most optimistic case was when yast not found the
hard disk %-[


Any ideas?

Best regars
