Z420 Workstation
Microsoft Windows 7 (64-bit)

Hi team,

Please help me, i have problem with Z420 Workstation PC that get error 110 out of memory space for option ROMs. First i had follow manual to disable all uneeded ROM (such PCIe 3,4,5, and 6), also i reset the BIOS by plug out CMOS batery for more than 5 seconds. I had try swap HD, RAM, and VGA card but there is in good condition in other PC. Is this fault related to the motherboard ???

Please suggest

thanks

some pci-e cards (like Raid controllers for example) have a onboard rom that is merged into the computers bios during startup.

 

each pci-e's cards bios will consume more of the available space that the mfgr allocated for this function if the total requested/used option rom space is exceeded you will get a error.

 

the solution is to either remove a pci-e card that has a bios rom thus decreasing the used option rom space used

 

and/or disabling some/all of the onboard peripherals such as the z420onboard lan's boot rom, and/or the onboard LSI SAS/SATA controller

 

disabling the option rom for pci-e slots that do not have a card installed is pointless as there is nothing to disable!!!!

 

try setting the bios back to factory defaults first, and then if nessary disable the onboard Lan boot option and if nessary do the same for the onboard LSI controller boot rom

Hi DGroves,

Kindly please advise also how to enable those setting,

Thank You very much for your prompt response
