#Correction ( 64 and not 128 ) Chip: Winbond 25Q64FV ( see attachment for BIOS-Dump and NVMe-Mod ) Model: SVP132A1CM BIOS-Version: R1045V7 BIOS-Release: 19.05.2015
#Repair BIOS after a bad flash ( this is how I repaired the bad flash )
1. Take the battery out of your Sony Vaio laptop 2. Connect CH341A Programmer Hardware 3. Start the CH341A Programmer Software ( Version: 1.29 ) 3. Click "Erase" 4. Click "Blank" 5. Click âLoadâ and select the original BIOS-Dump or other BIOS-Dump from the same machine model 6. Click "Write" 7. Click "Verify" 8. Boot into Windows and flash the latest BIOS from the Sony Vaio Homagepage
#Testing Windows: OK
1. Flashed BIOS+NVMe-Mod 2. NVMe-Drive is not visible in BIOS 3. Boot from UEFI-USB 4. Install Windows 10 5. Unplug UEFI-USB after Installation 6. Sony boots from the NVMe-Drive for some reason ( still not visible in BIOS; see attachment )
7. Check out the HwInfo after Windows10 installation on the NVMe-Drive
#Testing Linux (Manjaro): no boot I work basically on Linux, but after I boot into USB-Linux-Installer the NVMe-Drive is detected even before the BIOS-Patch, but the problem that I have, I canât boot after OS installation from the NVMe-Drive ( after I take out the USB-Stick ) Still I can boot from the USB-Stick and then select the EFI-Partition from the NVMe-Drive, but without USB-Boot, I canât boot into NVMe-Drive
#Testing several drives 1. Intenso M.2 SSD TOP 1TB -> works without BIOS-Mod as well 2. Samsung MZ-HPU256T -> works without BIOS-Mod as well 3. Samsung M.2 2280 SX8200PNP 512GB -> not visible in BIOS, works with Windows-Installation 4. Intel SSDPEKKF 256 G7L -> not visible in BIOS, works with Windows-Installation
#Questions 1. Why is the NVMe-Drive not visible in the BIOS?
2. Why is the Windows 10 installation working after taking the USB out, even if the BIOS is showing "no drive"?
We have to remember users, that this MOD is a simple insertion of DXE driver into bios structure, there is no more edit/strings inserted. This is necessary for the UEFI loading device and to display the NVMe class disk in OS setup. Ill say that about 75% of bios (MODS) do not show a NVMe drive or as some, a PATA device, this depends on OEM bios structure/strings/codeâŚand u dont need to mess around this for this simple insertion. The UEFI/GPT/x64 OS requirements does the rest and adds a boot entry that the UEFI bios boot manager will seek for. So thats wot u need to correct in ur LINUX installation
By the wayâŚshare with us and for future guidance, wot was the failing flash procedure that broke the system.
#UEFI: Windows (works) The Patch works 100% for Windows. Somehow windows does something and adds the Entry so the sony can boot from it with the NVMe-Disk inside. IMPORTANT: Once you have installed and booted from the NVMe and you take the SSD out for some reason and then put it back in, it will not work again; you will need to install the Windows from scratch
#UEFI: Linux (does not work) Installation was made state-of-the-art: GPT Partition table and EFI-Volume, yet under Linux it does not work
I have tried diff. distros and the same thing. I can boot from the UEFI-USB and install it, but after the installation there is no boot from the NVMe; I need to boot first from USB and then select the EFI-partition. Partition intallation:
Manual boot after installation:
Double and tripple checked the creation of the EFI/GPT for Linux:
Somehow windows is outsmarting us with something and adds/changes something in the boot section.
#Difference between SATA and NVMe (speed) SATA M.2
NVMe Intel
NVMe Crucial P2 CT1000P2SSD8 | check out the speeds on Linux Manjaro, its just insane
Very nice project and again thank you guys for the support.
#How did I break the BIOS-Chip? I have selected a wrong version of the chip when I wanted to write the ROM I have not clicked again read/check/erase/blank/write and I just selected ROM and hit the âwriteâ button -> my bad
Probably there is a way on how to use the UEFI/GPT+NVMe for Linux on this machine Any help is very much appreciated
