But after saving the moded BIOS, I reopen it to check, and it shows that the “NvmExpressDxe_5.ffs” module is not the last one, in fact, it swaps position with the empty named module just above it (the one with “00010018” bytes size and GUID “05CA01…”).
I don’t know anything about BIOS, but looking at the source and output files, I think the “NvmExpressDxe_5.ffs” file should be inserted at offset “006E0000”, the start of Volume free space, is it correct?
This is my calculation, based on the report from MMTool and from UEFItool user interface:
So I try to create the file myself here, by copying “NvmExpressDxe_5.ffs” file to the start of volume free space. File size remains the same, and volume free space size down an amount equal to the nvme file size. e7760ims.480.self.fd - Google Drive
Both MMTool and UEFItool shows Okay, but as I dont know anything about BIOS, so I am not sure. Pls help me to validate it.
Thanks for the links to the BIOS variants. Meanwhile I have checked them.
Here is my evaluation: You can flash the BIOS, which was modded by the AMI Aptio MMTool.
The NVMe module has been correctly inserted by the AMI Aptio MMTool as undermost “DXE Driver” without moving/deleting/inserting any Pad-file.
Good luck for the flashing procedure!
Please read the start post of >this< thread before you start doing that. You have to rename the BIOS file.
It is the undermost “DXE Driver module”. A Pad-file doesn’t count.
All modules of the compressed DXE Volume have been resized, because you have inserted an additional module. Since the total size of the BIOS must not be changed, the BIOS Tool enhances the compression of the DXE Volume and its components.
No, it is a “Raw” module (neither a “DXE Driver” nor a “Freeform” module.
You can verify it yourself by opening the BIOS with the UEFITool.
The AMI MMTools don’t show Pad-files.
You are right - my guide was not exact enough regarding your quoted sentence. To avoid any future confusion I have now replaced the words “undermost module” by the words “undermost DXE Driver module”.
I hope, that all your questions have been answered by me and you can now flash the modded BIOS.
I was lucky enough to find an experimental/incomplete uefi bios and this great thread for my old msi p45 motherboard. I know have revived an old pc, added a nvme boot drive with uefi windows thanks to this guide . I wonder if i could increase ssd speeds (my pcie adaptor supports 4 lanes i could use 8 lanes on this board’s pciex 16lane). Thanks, and happy new year!
PCIe lanes are the physical link between the PCIe supported device and the processor/chipset.
Assuming a common NVme 3.0 x4 disk:
You’re NVMe disk will only uses x4 lane bandwidth, regardless the adaptador mechanical design or PCIe slot mechanical design higher than x4.
Even so, as on your motherboard the PCIe generation is not 3.0 (8.0G/Ts), it will only use 2.0 (5G/Ts) x4 maximum speed.
You cant “squeeze” more from a old P45 chipset PCIe2.0
What you have now is the NVMe possible miracle on this motherboards generations and cant never
achieve the performance provided on the technology used in latest chipsets.
Correct me if i’am wrong the nvme and the adapter is sharing a pcie 3. x4 protocol. So the bottleneck is not between the adapter and nvme. The adapter is connected via pcie 2.0 protocol but the motherboard can deliver 8x lanes but the adapter can’t. So another adapter with 8x or 16 lane capacity and probably a good chip on it could deliver around 3400 mb/s r/w speeds.
in raid 0, yeah, if your nvme drive is a x8 ones then you could, but if its only at x4 3.0, unless the adapter could do raid 0 or the similiar one (thing is both nvme working as 1), then it wont as it works separately.
Since there is a gpu on my first pcie slot the second one and the first one will share 16 lanes meaning 8x lanes on pcie 2.0 meaning a theoratical speed of 4O00 MB/s each. Currently i’m running my nvme with an adapter capable of 4x lane pcie 3.0. This means the max i can get is 2000 MB/s speed for the nvme. But an adapter which can fully use the 8x lanes provided by the motherboard can transmit at a rate of 4000 MB/s to a 8x or 16x adapter. And if the adapter can provide at least 4x pcie 3.0 lanes to the nvme could transmit at 4000 MB/S to the nvme (assuming pcie 3.0 speeds between nvme and adapter).
İn my case i really think that the adapter is the bottleneck. İf i could find an adapter which can fully use the 8x lanes i could reach twice the speed i’m having right now (assuming no other bottlenecks from the cpu/ram side).
I have successfully flashed the mod BIOS, I can see PATA in the boot list.
Now I am installing windows on it. Thank you very much!
I dont see a MSI flash guide on your topic. I believe that this guide from MSI site is great, the tool is MSI forum flashing tool. Pls read it and update to the flashing guide topic if you find it good.
This guide has previously helped me to recover failure BIOS flashing 2 weeks ago (totally washed out, even serial & MAC address). I used this guide to flash the mod BIOS.
Go read Step3 Additional notes… dont want to call you a blind user anymore…you’re going to start hating me soon and joining my fans list, but yeah the guide is for reading!
Oh and dont forget Step 4…humm?
