show nvram:startup-config isn't working

simply

Have C2950T

ICND1 odom book says following should work:
1) show startup-config
2) show nvram:startup-config
3) show running-config
4) show system:running-config

I can do following:
1) show startup-config
2) show running-config
3) dir nvram:
4) dir system:

Following fails:
1) show nvram:startup-config
2) show system:running-config

I've cut and pasted output below

SGSW1#dir nvram:
Directory of nvram:/
29 -rw- 1237 <no date> startup-config

SGSW1#dir system:
