Well I did a bit of digging, and it's not detecting because there aren't actually entries in LSI_MR3 for the 9240-8i
According to the KB page, it should be a "VMware Inbox, Native" driver and come bundled with 7.0
My test install of 7.0b reported the version that's supposedly required "7.712.50.00-1vmw.700.1.0.15843807"
VMware Compatibility Guide - I/O Device Search
Digging through LSI_MR3.map and lsi_mr3.ids I do not see it listed, The only thing remotely close is the Perc H310
regtype=native,bus=pci,id=1000005f10281f4e......,driver=lsi_mr3
regtype=native,bus=pci,id=1000007310281f4e......,driver=lsi_mr3
regtype=native,bus=pci,id=1000007310281f50......,driver=lsi_mr3
regtype=native,bus=pci,id=1000007310281f51......,driver=lsi_mr3
regtype=native,bus=pci,id=1000007310281f52......,driver=lsi_mr3
regtype=native,bus=pci,id=1000007310281f53......,driver=lsi_mr3
regtype=native,bus=pci,id=100000ce..............,driver=lsi_mr3
I'd expect to see 1000007310009240 in there.
I wonder what would happen if I forcefully added the HWids into the LSI_MR3 tables, using the following guide as a reference....
