Every time I boot Knoppix it says that I have not enough memory to run kde and starts on another desktop, I have 512 DDR400, I think its enough, what's happening?
The memtest is OK and it happens both in kernel 2.4 and 2.6.
Anyone know how to fix it??

The computer is an athlon 2600+, asus a7v600, fx5200, 512mb ddr400... and no HD at the moment, maybe this is the problem???

Thanks in advance and sorry if my english is so bad
