abt Compaq Smart Array 642 (well HP really)

It should work, lets take a walk through src land..

cd /usr/src/sys/dev/ciss
less ciss.c

this is what we find.

    { 0x0e11, 0x4070, CISS_BOARD_SA5,   "Compaq Smart Array 5300" },
    { 0x0e11, 0x4080, CISS_BOARD_SA5B,  "Compaq Smart Array 5i" },
    { 0x0e11, 0x4082, CISS_BOARD_SA5B,  "Compaq Smart Array 532" },
    { 0x0e11, 0x4083, CISS_BOARD_SA5B,  "HP Smart Array 5312" },
    { 0x0e11, 0x409A, CISS_BOARD_SA5B,  "HP Smart Array 641" },
    { 0x0e11, 0x409B, CISS_BOARD_SA5B,  "HP Smart Array 642" },
    { 0x0e11, 0x409C, CISS_BOARD_SA5B,  "HP Smart Array 6400" },

so yes, it "should" work :)
