Thank you mobilenvidia

I knew how another roms affects LSI card but found few other interesting things.
I use RAID mode on Intel rom (Raid0 4xHDD + SRT SSD in future) and SATA/IDE mode on Marvell (IDE for CD/DVD booting) and this modes didn't affect my LSI card working in any way. But disabling Marvell boot option or just a whole controller are the only ways to access WebBIOS, next move is like you said a little tricky. F11 right after start (but without CTRL) which after some lag gives an access to boot device selection, choosing RAID: PCI ROM Setup, B02 D00 F0 (in fact my LSI 9240-8I card) and right after F11 when I see some LSI bios rom identification, press CTRL+H just like info on screen is recommending to do.

Second interesting thing to me is that webBIOS access is not equivalent to LSI bios booting option, webBIOS is accessible almost all of the time (except when Marvell boot is active) but even if I disable in webBIOS "Controller BIOS" option I have access to webBIOS after restart/shutdown. So I conclud that "Controller BIOS" is just boot from LSI option ?

Tried EASEUS Partition software already (which has also some recovery options) but now EASEUS Data Recovery is scanning my drive, so there's few hours of waiting for me.

Sad things is that my system previously booted from OCZ V3 SDD in 30-40 seconds, after installing LSI card - two or even three times longer and even disabling other controllers, other bios options and LSI controller bios didn't helped much.

My another question is if I previously connected some HDD to LSI controller and made a virtual drive, and now to the same port connected different HDD, should I make another virtual drive and delete previous one ?
