So only 1 out of 3 drives discovered.
And this is the one which doesn't need Promise metadata on it at all.

The other 2 the OS fails to access so far should have Promise metadata though.

Interesting:
a flaw in dmraid status settings it seems. That shouldn't say "ok",
unless your metadata raid.total_disks member contains 1 (see "dmraid -n"),
which is not to be expected :(

BTW: in case you want to get rid of the Promise metadata on hdc,
     run "dmraid -rE". Send the output (*.dat and *.offset files
     created in working directory) to me, please.

Hrm, sata_promise is the correct SATA driver for this chip but
I'ld expect /dev/sd namespace for it.

Please check the kernel log.

First you need to get access to the 2 drives on Linux, then we can
check if there's Promise metadata (presumaby you've set thme up using
the Promise BIOS) on them.
