IBM BladeCenter BIOS Post Error

After upgrading the BIOS to the latest revision of several HS21 blades in the IBM BladeCenter H Chassis, I began to see several errors during system boot / post.

POSTBIOS: 00182100 000000Q
00182100 00000000 iSCSI/BOFM error

The solution was to update the HS21 Baseboard Management Controller (BMC) firmware as well. I applied both updates using the bootable CD ISO's provided by IBM. You can find the BIOS and BMC Firmware here... http://www.ibm.com/support/fixcentral/
