I hate to recommend reading, but this is from the english.txt file of Comet
version B05 found at Frank's site:

10. ENDGAME TABLE BASES
-----------------------
   With version B.03, Comet supports the 5 man endgame table bases
   by Eugene Nalimov, who is btw also author of "Siberian Chess".

   DOS: for the DOS-version COMET32.EXE, the DOS environment variable
      "tb_path" has to be set prior to program start. It has to point
      to the directory containing the table base files. This can be
	 set tb_path=c:\edb
   WINBOARD: there are 2 new additional lines in the init file "comet.ics"
      of the winboard comet COMET-WB.EXE
	 TB_PATH: c:\edb
	 TB_CACHE [nr of megabytes]: 4
      The 2nd entry defines the size of memory to be used as a table base
      cache (to decrease the number of "painful" hard disk accesses).
      This value plus the value for HASH_MAX plus 1 MB for the program
      itself can be expected to yield the memory use of Comet
   The DOS-version always uses 4 MB for this cache.

   The table bases will be also supported in their compressed format.
   For the DOS-Comet, these files must be renamed:
   e.g.   rename  kpkp.nbb.emd  kpkpnbb.emd
   and so on.

   The DOS-Comet ("COMET32.EXE") can get problems with auto232 when
   the table bases are being heavily accessed. Installation of a large disk
   cache (10 MB or more) with SMARTDRV may help.

   Table bases in the compressed format can be downloaded from the web
   page
	   ftp://ftp.cis.uab.edu/pub/hyatt/TB
