Knoppix it doesnt work on Pentium Pro with 128MB RAM

Hello Someone

i tried in the last time to startup knoppix on my old PC.
But on the titel "Autoconfiguration" and the line is complet, the PC is ?hang-up. The only solution is, to reset the system.

Could someone give me a hint ?

I try to start with failsafe, knoppix no pcm and/or mem=128. but nothing is working.

my hardware:
Pentium Pro 200Mhz, 128MB RAM, 2HD-SCSI, AHA-2942Ultra Wide SCSI, 1 DVD-ROM, 1SCSI-CDR Burn, Viper Diamond 550 with 16MB PCI.

greetings
