Request for barebone EMB-S280R4-M

[Radeon24]

Hi everyone,

I need your help to unloke a feature on this barebone : http://www.pcpsol.com/index.php?m=Products&a=show&id=108

That's a PC Partner computer, the same board than a Zotac MA760.

I want to use the computer with ESXi, but the IOMMU / SR-IOV functions seems to be disabled in the bios.
The bios is an Aptio V (dump attached), and actually I think I found the good setting with AMIBCP in PCI Subsystem Settings / SR-IOV Support.
But, the tab PCI Subsystem Settings is a the same level than Setup, and after changing the Access / Use parameter to USER, I can't find the menu.

I also extract the modules Setup and PciDynamicSetup with MMTool, but in PciDynamicSetup there are no options Enabled / Disabled but checkbox :

Code:

0x65E8 Form Set: PCI Subsystem Settings {0E A7 04 F3 A9 AC E2 21 52 48 98 75 7F F4 88 1D 67 A5 06 00 02 00 01 71 99 03 93 45 85 04 4B B4 5E 32 EB 83 26 04 0E}

0x6645     Var Store: 0xCCCC[6] (PCI_COMMON) {24 21 04 F3 A9 AC E2 21 52 48 98 75 7F F4 88 1D 67 A5 CC CC 06 00 50 43 49 5F 43 4F 4D 4D 4F 4E 00}
0x6666     Form: PCI Subsystem Settings, Form ID: 0x1 {01 86 01 00 06 00}
0x666C         Subtitle: 00.00 {02 87 3C 00 00 00 00}
0x6673         End {29 02}
0x6675         Subtitle:  {02 87 02 00 00 00 00}
0x667C         End {29 02}
0x667E         Subtitle: PCI Settings Common for all Devices: {02 87 07 00 00 00 00}
0x6685         End {29 02}
0x6687         Checkbox: Above 4G Decoding, Variable: 0x3 {06 8E 0C 00 0D 00 06 70 CC CC 03 00 10 00}
0x6695         End {29 02}
0x6697         Checkbox: SR-IOV Support, Variable: 0x4 {06 8E 10 00 11 00 07 70 CC CC 04 00 10 00}
0x66A5         End {29 02}

So now I don't know where to go, and I don't have the skills to analyse and modify directly the hexa in the bios.

I already look at the Zotac MA760 bios but this one does not even have the menu PCI Subsystem Settings !

Can someone look at this and try to help me please ?

Thank you in advance .

Hi,

In the meantime, i've contacted the PC Partner support, but they say that there is no other bios version for this hardware... I've done other resarchs with AMI tools but with no luck.

Can anybody has any idea to modify the bios in this way ?

Thank you .
