id imagine it means
1.7 = 1.7 Ghz
400 = 400Mhz FSB
And i think
2M = 2MB cache (l2)
the cpus in the inspiron 6000 series are both 400 Mhz and 533 Mhz FSB as i believe quite a few pentium 4s of that era did
you have an L2 cache of 2 MB what you are talking about is the L1 cache which is not 64 KB but infact 32 KB
You may be thinking of the bus width or something, just for you to confirm, i just found the manual for the inspiron 6000
