PackartBell TS11HR key behavior change

[gouster3]

Hi. i have PackartBell TS11HR. Im already using Modded bios for Acer 5750G (which is also P5WE0121 as my PackartBell) by Akbar.
Everything works well.
But, i have installed Aspire 5810t backlit keyboard. I would like to use that keyboard layout. (like Home key, PgUp, PgDn, End, fn keys...)
because they have all special keys differnet.
FN + arow up on keyboars should be vol+, and PdDn key should be pgnd. but now fn+arrow up dows pgup, PgDn appears like vol+.


and on top of it, packartbell has different layout as Acer on same bios file. (even logo is still packartbell)
so even im using Acer bios to have at least little bit better keyboard layout, nothing changed.

Can be keybard layout of Aspire 5810t used in TS11HR?
