Shadow RAM can't be disabled

["Mark A. F." <maflistbox@earthlink.net>]

Hi.  I am not able to disable shadow RAM through the BIOS on my IBM Aptiva 2161 Pentium 166 PC.

Here are the forced Shadow RAM settings:

    F000 - FFFF (System BIOS)
    E800 - EFFF (Rapid Resume BIOS)
    E000 - E7FF (System POST) 

    Upper Memory Boundary F200

I am working through my installation of Debian.

What misbehaviors might I experience due to these settings?

Thanks,
