I am looking to upgrade my VXIpc-650B from 166 MHz to 233 MHZ. I have the processor. I have another unit that is already 233 MHz and the NI board part numbers are the same 184466C-01. I just need to update the BIOS because the old BIOS wont display the max processor clock speed. It will only show 175 MHz. I checked the NI ftp site, but there was no BIOS update listed for that particular module.
On boot up, the controller only says: National Instruments VXI/VME-600 Series 5/10/98. Usually the NI embedded controllers say the BIOS version in this same line on text on boot. However, this unit does not.
If I hit DEL on boot, the AMIBIOS is version 1.05.
Sorry for the delay. There is not a BIOS upgrade for the VXIpc-650b; the same BIOS was used in both versions of the controller. Your controller should work fine even though the speed shown is incorrect.

However, I have seen other VXIpc-650b units with larger hard drives and faster processors and they display correctly in BIOS. There may not be a BIOS update utility, but I do believe that there are different versions of the BIOS.
