Specifications

Vendor: This is an abbreviation for the vendor of the board. The
sample report shows that the motherboard and the boards in slots
4 and 6 are sold by Epson. Note that this column merely interprets
the vendor information given in the first four digits of the EISA ID
column.
Prod#: This field contains the product number of the individual
board. These numbers are assigned by the vendor and should be
explained in the documentation that accompanies the board.
Rev#: This field contains the hardware revision number for the
board.
EISA Ver: This field contains the EISA version number. Each
motherboard is encoded with a version of the EISA specification to
which it conforms.
Note
The eisa command reports only on EISA boards, not on 8- or 16-bit ISA
(XT/AT) boards.
Eisa diagnostics return a 0 value if successful. A return value of 1
indicates a command line error, a return value of 2 indicates that
the motherboard was not located, and a return value greater than
2 indicates an unspecified error. If the slot number that you
specify is larger than the actual number of slots, the results are
unpredictable; however, the return value is still 0.
