Hello good morning, I have an HP Pavilion Slimline s5-1225la desktop

BIOS version: 7.16 Rev. A
Release Date: Aug 14, 2012
Filename: sp58264.exe (2.86 MB) Link: https://ftp.hp.com/pub/softpaq/sp58001-58500/sp58264.exe

The problem I have is that this version of the BIOS does not detect an M.2 SSD disk per PCIE x1 port, since I want to install the operating system on this unit to boot.
In the disk manager if it detects me, but when I want to boot this disk in the BIOS, it does not detect it, only the hard disk per SATA port and the operating system installation USB memory, I do not know if they could me modify the BIOS to detect the SSD by PCIE port.

ES COMPATIBLE CON LA PLACA MS-7525 BOSTON?
MUY AGRADECIDA POR TU RESPUESTA!

@melisa008 ,no, this BIOS is for Cupertino-H61/Cupertino2-H61 motherboards. HP used MS-7525 for building their Compaq dx2390, Compaq dx2420 Microtower PC, Compaq Presario SG3540IL Desktop PC and many other. So, you can install their BIOS.
