@Dziubek : Welcome to the Win-RAID Forum! The NVMe module has been inserted into the correct location, but unfortunately the used BIOS Tool has created a Pad-file, which is natively not within the BIOS. Here are the related pictures, which show the difference between the original BIOS (left Pic) and the modded BIOS (right Pic):
Questions: 1. Which BIOS modding tool did you use? 2. How did you flash the modded BIOS? 3. Are you sure, that the flashing procedure was successful (a failure would have been better in this case)?
Regards Dieter (alias Fernando)
Update: This is the related picture I got after having inserted the "small sized" variant of the NVMe module by using the AMI MMTool v4.50 (there was not enough space for the bigger sized one):
1. I used UEFITool to mod the bios. 2. I flashed the bios using AfuDos. 3. Yes because after I flashed MOD.ROM I downloaded this bios using AfuDos and checked this bios in UEFITool and I got information that the bios has line with nvmExpressDxe 4.
@Dziubek : Have you seen the "Update" within my last post? I recommend to flash the original BIOS before you are going to flash the correctly modded BIOS.
@Fernando , Yes I can see it now but I donāt know what it gives us. I also tried to change with MMtool but the information appeared āfile size exceeds the volume sizeā. Do you think that this āsmall sizeā will be correct?
Hello everyone. Hi Fernando. Finally I can say that I have had success with the H81 M-E motherboard. Here are some pictures. Unfortunately, the adater only supports running PCI x4 and this standard can only run PCI 2.0 on the ASUS H81 M-E motherboard.
Hi there sorry hate to ask a dumb question but I found a file folder on my desktop for this file G771JMAS.203 and wondering what it is for? I googled it and it brought me to this forum. I do have an asus lap top Thanks for the help
I would have help to ask who can help me, I have a pc with a Sabertooth P67. I had an m.2 SSD available and bought a pcie adapter to use it on this motherboard. I installed the bios modified by jaaa1976, I launch the installation of windows 10 from bootable usb but I cannot see the m.2 disk to start the installation. can you tell me where am I wrong and which parameters on the bios should I check?
@zazzazenigata : Welcome to the Win-RAID Forum! You should better ask jaaa1976 for help. This is the thread for users, who are doing the BIOS modification themselves. By the way - do you see a device named āPATAā listed within the āBOOTā section of the BIOS? If not, there is something wrong with the modded BIOS or you didnāt get it successfully flashed. Regards Dieter (alias Fernando)
thanks for your support but someting not work, I had update bios with yours link and all succesfully. But I canāt find the pcie m2 ssd.
Some setting of my bios is: PCI Express X1_2 Slot Configuration = U3 Mode (alternative X1 Mode) Marvell Storage controller = AHCI Mode PCI ROM Priorty = EFI Compatible ROM (alternative Legacy ROM) Option ROM Message ) Keep Current (alternative Force BIOS)
@Dziubek : It is not enough to insert the NVMe module into the BIOS - this modded BIOS has to be successfully flashed!
Only users of a mainboard with natively full NVMe support will see the NVMe SSD with its model name within the BIOS. After having successfully flashed the properly modded BIOS the NVMe SSD should be listed as drive named "PATA" within the "BOOT" section of the BIOS (provided, that the NVMe SSD has been correctly inserted).
Hello everyone, Iād like to thank Fernando and Lost_N_BIOS for a great tutorial. Thanks to these tips, I was able to mod the bios for the ASUS M5A99X motherboard! I used a WD Blue SN550 SSD and an SSD M.2 NVMe PCIEx X4 / X8 / X16 adapter. A few words about the BIOS installation itself. First, I ran and checked the correct operation of the SSD in the adapter on the original BIOS (M5A99X-EVO-R20-ASUS-2501). The drive should be visible in Windows. I formatted it for checking. As the Asus motherboard supports max. PCI 2.0 x4, so the speed oscillated around: write - 1200MB / s, read 1600MB / s. Then I uploaded the modified BIOS. The only way is to upload the BIOS via USB Flashback port and using flash button on the motherboard. After flashing the BIOS, do not look for the disk in the BIOS, you will not find its presence anywhere. We select the UEFI boot option from PCIEx and run the Windows installer. After the first reboot, Windows should boot from the M.2 NVMe disk. After entering the device manager, the NVMe controller is visible. Sorry for my English, I used a translator
@wongregor : Welcome to the Win-RAID Forum and thanks for your report! It is fine, that you succeeded.
Lost_N_BIOS helped a lot of people, but the procedure about how to get full NVMe support for old systems was developed and the related guide (= start post) was written by me alone. Enjoy the performance boost of your "old" system! Dieter (alias Fernando)
