After Windows 10 installation no access to BIOS

[Peter_Altmayer]

Hello World,

recently I updated my OS to win10 and since then I can not access the BIOS anymore. I tried "Esc", "F1", "F2", "F8" and "F10" and probably every other of the keys just in case. Nothing works. Before though, on win8, it worked with "Esc". I already downloaded the HP Support Assistant program, but it does not help me. I thought maybe I can update the BIOS with the help of that tool. I tried to get the BIOS update file from the HP drivers website, but for my machine I can not even choose win10 in the drop down menu. 
Here are some Numbers, combined with letters that might tell you what I have and hopefully helps you to help me...:

System Model: p6-2282l

OS Name: MS win 10pro (64 bit)

BIOS Version/Date: AMI 7.05, 2/5/2012

BIOS Mode: Legacy

BaseBoard Product: 2ABF

System SKU: H1Q21AA#AKL

Hopefully there is someone out there who can help me. My initial goal actually is to enable the "Wake on Lan" function, so I can start this computer remotely via TeamViewer. Maybe there is an other way to turn that on which does not require to access the BIOS. Thank you for your time and help!
