Question:
I am getting runtime error 255 when using Delphi 3. What 
does it mean?

Answer:
 This error is reported if there is a hardware or other exception
 that isn't caught (and that is not one of the error codes listed 
 below). As of this writing, Error 255 in Delphi 3 appears to be
 caused by certain video drivers, or by workstations using the
 AMD NexGen x586 CPU. If your PC is not using the AMD NexGen x586,
 then the problem is probably the video driver. Try changing
 driver configuration, getting a newer video driver, or using
 the generic S3 drivers provided by Microsoft or S3 Inc. 

 In the case of the AMD NexGen x586, AMD no longer officially
 supports it, but there is a "Windows CPU Identifier tool" reported 
 as fixing this runtime error in a file called "winid20.exe", pack-
 aged in an Update Kit called  ftp://ftp.amd.com/pub/nexgen/updtpi31.exe  
 (this "update kit" is actually a self-extracting executable file, from 
 which you extract, and then execute, the "winid20.exe" tool. For further 
 details, please refer to AMD's  
 http://www.amd.com/products/cpg/nx586/support/toolbox.html 
 Nx586 Processor Toolbox  home page.)

 Note: if your PC uses the VESA Local Bus instead of the PCI bus,
 you'll want to download the package ftp://ftp.amd.com/pub/nexgen/updtvl30.exe instead.
