	Does anyone know what the ST and EF numbers in unix.log mean?

	i.e.

HDERR ST:51 EF:10 CL:FF6A CH:FF01 SN:FF00 SC:FF02 SDH:FF20 DMACNT:FFFF
DCRREG:F0 MCRREG:D100 Thu Jul  7 02:07:35 1988

drv:0 part:2 blk:3760 rpts:1 Thu Jul  7 02:07:36 1988

HDERR ST:51 EF:10 CL:FFB3 CH:FF00 SN:FF00 SC:FF02 SDH:FF21 DMACNT:FFFF DCRREG:91 MCRREG:9300 Tue Aug  2 12:45:03 1988

drv:0 part:2 blk:839 rpts:1 Tue Aug  2 12:45:05 1988

	ANY hints would be appreciated. Do the numbers relate to the status
	definitions in /usr/include/sys/gdisk.h?
