If all is configured correctly, you can just do:
  BDI>rd esr
  esr : 0x00000000  0
If not, but you know the SPR number, you can just do:
  BDI>rdspr 0x3d4
  SPR  980 : 0x00000000            0

The BDI came with a file called reg405gp.def.  This file contains the
mappings from names to spr/dcr numbers.  Make sure it is in your tftp
directory and then make sure you have something like:
  IDCR3	0x014	0x015	;KIAR and KIDR
  FILE	reg405gp.def
in your config file.  BOOT your BDI and you should then be set.
