Solaris, SCSI M.O Drive on x86

Hi, i'm trying to install a MO Disk Drive Sony model: SMO-f541, to read a 2.6gb Magneto Optical Disk, I install Solaris 10 in a x86 machine with these specifications:
Desktop Board Intel*D946GZIS
Intel core 2 duo 4300, 80ghz
Ram 2038
hard disk 250 gb
I have a PCI SCSI card AHA-2940UW,
At the beginning I have a trouble with the grafic card, but following this tutorial I had the window mode. 8. X Windows (Solaris x86 FAQ)
Later I install the driver for the AHA-2940UW, following this pdf
http://www.adaptec.com/en-US/support/\_eol/sun/AHA-2940UW-OF/\_docs/aha294xuwof\_ug\_pdf.htm?nc=/en-US/support/\_eol/sun/AHA-2940UW-OF/\_docs/aha294xuwof\_ug_pdf.htm
I downloaded the driver called: 7800_fw_v200_sol.dd
I use too this manual http://dlc.sun.com/pdf/816-4468-10/816-4468-10.pdf
but I don't have the (cXtXdXsX) then I cant use the �mount�
I found this manual for the optical drive, but I dont understand it: http://www.sony.com.au/objects/AAASupport/Guides/4\_X\_Guide_aus.PDF
I did all of this but Solaris can't see the MO Drive, What can I do?

Thanks!!!
