Whats up guys?

I used to use Softice in XP, but now I have a new desktop with a 64 bit processor, running a 64 bit version of windows. I checked out syser debugger (www.sysersoft.com), and it looks okay, but I was curious what else is out there?

P.S. Which debugger is best for vista in general? 32 or 64 bit?
P.P.S. I'm aware of IDA 64, but it's user level(?), not kernel.

I'm not trying to be negative, but from what I have seen people usually use a dual-boot or a VM to use olly/sice to debug still.

i'm pretty sure syser won't run on a 64-bit system

windbg for x64 kernel debugging, or ida for x64 r3 debugging. Note that ida can't debug localy x64, you will have to run x64 debugging server (it's located in ida folder) as idag.exe will run in wow64 (it's x32 exe no matter if you use x64 or x32 version, it only influences x32/x64 disassembling, while both exes will run in wow64)... also I doubt it will support local graphic x64 debugging in a near future as it's writen in Borland C, and as far as I know there is no Borland x64 compiler maybe if they move GUI to QT they will get portability...but...

Thanks for the input guys. Should save me from banging my head into my desk . Windbg looks like a winner, thank you deroko.

I use Olly with the 64-bit plug-in and it works quite well despite that it is r3.

yes, it works but only for x32 binaries, and not x64

Yeah that's fine. I'm not expecting to work on any 64 binaries in the near future anyway .
