Hi,
Also seen on a NEC server, a 1068 chip with a jumper used to switch chip
PCI ID and its BIOS:
- PCI ID = 0054 => 'MPT Fusion' BIOS
- PCI ID = 0055 => 'MegaRAID' BIOS
I'm feeling that I submit this unusual chip ID to pciid DB some month ago...
More important: there's a driver for this chip when it is used in
'MegaRAID' mode (standard 'mptsas' driver may be used for MPT Fusion
mode) . This driver is named 'megasr' and is available (binaries) from
several server vendors (Intel/Supermicro/Hitachi...) for standard distro
(RH,Suse).
Seems that this driver is provided by LSI (modinfo)...
regards
