PRB: Windows CodeView Displays ????:???? for Memory Values

ID Number: Q66655

WINDOWS

SYMPTOMS

When the Microsoft CodeView for Windows window-oriented debugger is

used to display memory with such commands as the following,

CodeView for Windows displays question marks rather than the values

contained in memory:

dw 0000:0000

CAUSE

0000:0000 is not a valid protected mode address. The 0000 value is

a legal protected mode segment register value, but it is not a

valid segment selector.

RESOLUTION

To display memory at real mode addresses, such as "0000:0000", use

a debugger that can interpret real mode addressing, such as

WDEB386. WDEB386 is provided with the Microsoft Windows Software

Development Kit (SDK).
