The Adaptec 6405/6805 RAID controller will be not recognized and didn´t start in the system during a reboot (Alt-Ctrl-Del and power button).
Only when we remove the power cable and start again the controller starts.
We had different systems with the S1200BTL board in a SR1304 system and Chenbro chassis.
Configurations is with the E3-1230/1240 CPU and 16 GB RAM.
All with the same problem.
Same error here. Talked with Adaptec and made a few changes to bios settings, but still no fix. Escalated to next support level with Adaptec.
It's not on the approved list of raid adapters, but still hoping to find a resolution.
We got from Adaptec the information, that BIOS 27 and the controller in slot 3 (x8) will function.
But we can´t test it, because BIOS 27 is still not on the Intel support pages and we have the R1304 rack chassis with a riser card.
Are all your hard drives connected to the RAID controller? If not, I've seen other users mention that the controller will not appear if you use other HBA/RAID controllers, including the ones on the motherboard.
