debian-31r0a-sparc-binary-x not booting correctly on SS20

[Donald Parsons <dfp10@capital.net>]

My debian-31r0a-sparc-binary-1 CD image installs completely without error . 
On removing the CD and booting the install fails as follows:
calibrating delay loop
2 CPUs activated
kencpd    16 RAM disks of 8192k size
loading 2140 blocks in ram disk
memory 2140k freed
cramfs: wrong magic
Kernel panic:UFS unable to mount root fs on 00:12

I then do STOP A  OK> boot
boot: Return

I have tried several to get boot: to accept new memory sizes 
(ramdisk_size=16000 and mem-512M ) without success.
Do I have too much or too little memory?
Can someone advise me on the kernel panic and the memory problems?
Thanks
