SYSTEM BOARD EXTENSION ACPI BIOS ERROR

I have Win 98SE
I installed 128Megs PC100 SDRAM & when I
rebooted my system, I rec’d this error
System Board Extension ACPI Bios in
Device MGR. Code =15 (OXF) Alloc Resources
NONE The system recognizes the 128 Megs

What does this error mean?
Is my Ram ok to stay in the system or
should it be removed?
