The LSI Sata Megaraid 150-6 and Intel SRCS16 are exactly the same
card. The PCI Vendor and Device IDs might be different, but they
should both still work with the Megaraid driver (The LSI definately
does). They are identical down to the BIOS and firmware versioning on
the cards.
The LSI 150-4 is just the 150-6 board with 2 Sil3112A chips driving 2
sata ports each.
The Intel SRCS14L is not directly related (from what I can see from
visual inspection), though it does seem to share much the same
hardware, even if the boards differ in layout.
