Hi, I have a box that is celeron 655 MHz with 128 SDDRAM and 3 GB hard disk.
I try to install Suse Professional 9.1 in my CPU. At the beginning, there is ok from the installation wizard. I selected the partition as follows;

Primary Swap 512MB
Extended /boot 100MB
Extended / 512MB
Extended /var 512MB
Extended /usr 512MB
Extended /home Remaining disk

After the wizard running formating on the disk, then it prompt out an error, showing /dev/hda6 unable to mount. but I am sure the disk is ok because I have the Microsoft Windows 98 installed before.

Is there any limitation on my hardware? Do I partition wrongly? Please advise...

I am still rather new to computers but from reading your post , the extended partitions are eatng up your space for the
operating system. You probably will need a larger drive.

I think the problem is the same as me. The kernel isn't load the reiser-fs modul.
YaST is format the part. with REISER file-system, but YaST (sometimes) can't mount this reiser!
The reiserfs modul is missing!
YaST Error-msg: "Can't mount /mnt" or simulary

follow this instructions:

1. boot from your boot device
2. Manual Installation
3. set your language and yor keyboard settings
4. select "Kernel Modules (Hardware Drivers)"
5. select "Load File System Modules"
6. load modul "reiserfs: ReiserFS"
7. go back
8. Load other hardware modules when needed
9. start the installation with YaST

Hope this helps!
Good Luck ;-)

(Problem is shown at Suse 9.1 and Suse 9.2!)

512 MB is indeed very little space for SuSE 9.1. It may be sufficient for a minimal selection. With such a small HDD, you waste too much space by creating extra partitions for /var, /usr and /home. Keeping everything under / is much more flexible. Also, 128MB RAM is hardly sufficient for KDE3.

But this does not explain why /dev/hda6 is unable to mount. Do you see more messages, when you switch to text-console (Ctrl+Alt+F1) or to the kernel messages (Ctrl+Alt+F10/F11)? (To get back to graphical console, press Alt+F7)

EDIT: 100MB for /boot is far too much. I have 3 kernel installed and use 14MB. Include this into / also.

I think your better do this partition sizes:

primary "swap" 256MB
primary "/boot" 100MB (only needed when you start from an other OS-Bootloader as grub)
extented or primary "/" the rest of space

Note: The complete installation of 9.1 Prof. needs over 3GB!
Select only "graphical Installation with KDE"

Thank you for your advice but there is something confused me...
Could I put the /boot into / directory as only swap and / space occupy whole hard disk?

Yes... I am using reiserfs filesystem type. I think this is the same problem with you.... Thanks for your solution. I will try this weekend.....thanks

Yes. If you choose to have only / it will contain everything except swap. This is what the SUSE partitioner usually suggests: one partition for / and one for swap.

I have loaded the kernel module of reiserfs. I think this time is not the file system module problem.
After the Yast format and partition the hard disk, it switch GUI mode to text mode and prompt up as:
Segmentation fault at partitioning /lvm_pv_lib.ycp :1703
/usr/lib/YaST2/bin/YaST2:line 525 :1451 Segmentation fault ....

What is problem here? Please advise me....thanks!!
