- Guide for crossflashing 12th gen Dell Mini Mono & full size cards to LSI IT firmware.
- Supported cards include H310, H710, H710P, and H810 models in both Mini Mono and full-size variants.
- Reasons for crossflashing: Better performance with increased queue depth and different driver compatibility (mpt3sas vs MegaRAID).
- Preparation steps: Disable specific BIOS settings (Virtualization, SR-IOV, I/OAT DMA), set boot mode to BIOS, remove RAID battery, and disconnect all drives.
- Download provided ZIP containing FreeDOS and Debian live ISOs with necessary tools.
- Identify card revision using the 'info' command in FreeDOS and follow the corresponding guide.
- Warning for blade servers: Use only the 'for blades' section if applicable.
- Optional: Disable ThirdPartyPCIFanResponse to avoid fan speed issues using IPMItool or RACADM.
- Revision differences: D1 supports PCIe 3.0, B0 supports PCIe 2.0; P models have more cache (irrelevant in IT mode).
- Part numbers listed for various card models and revisions.
