This guide allows you to crossflash 12th gen Dell Mini Mono & full size cards to LSI IT firmware. Mini Mono refers to the small models that fit in the dedicated “storage slot” on Dell servers. Because iDRAC checks the PCI vendor values of cards in this slot before allowing the server to boot, the generic full-size PERC crossflashing guides do not apply. This guide however solves that issue. Technical explanation for those curious. The following cards are supported:
- H310 Mini Mono
- H310 Full Size
- H710 Mini Mono
- H710P Mini Mono
- H710 Full Size
- H710P Full Size
- H810 Full Size
