Hi All,
I want to try writing file system filter driver. I have a little knowledge on writing device driver. Unfortunately I have only one machine, I know softice can provide kernel level debugging on the same development machine, I tried to install driver studio 2.7, but getting BSOD in ntoskrnl.exe while startup. Iam using WinXP, compuware driver studio 2.7.
I tried even in win2k, but no luck. Do anyone faced the same problem? Is there any other tool can replace softice?

If you have access to vmware us it. That will allow you to use windbg.

Buy a second machine, trying to do any file system work in a single machine
configuration is idiocy of the highest level. You are way to likely to
corrupt your build tree, and the time wasted in boot to run the dev
environment, reboot to test cycle will more than pay the cost.

Hi,
I tend to agree with Don on this one. I used to use softice all the time as
my debugger but had no end of problems when I started to develop filter
drivers. As Don said, buy another machine. You will save so much time.

You do need to note that that’s capitalistic view - not shared by many dare to
endure in this area:-) (No, not going into politics, just pointing out that you have
to understand other people’s idiocy - they might be the idiot you’re gonna call boss

Sorry, the last time I was forced to use SoftIce for such a project I asked
the VP of the division to drop by my office to watch me work. After he saw
the time wasting cycle of booting for debug, hit a problem, reboot to modify
and rebuild, and reboot, he quickly ordered test machine. And this was in a
very tight economy.
All it takes is one corruption and subsequent loss of work of a single
machine setup to convince any rational manager (including most pointy haired
one’s) that single machine debugging of a file system compnent is a bad
idea.

If all else fails, you can always use VMWare for a virtual machine, and
that does currently allow debugging. Perhaps with Microsoft’s
acquisition of Connectix, that will emerge as another alternative. The
cost of Vmware however is not so far off from a second machine.

I buy my cables at the local Staples, I just checked there isn’t one in
Frankfurt but there are nine in Germany. Unless they have a radically
different policy than the US and Canada, they promise if the store doesn’t
have an item they ship it to the store for free.
I’ve tried SoftIce both local and remote and found it much more likely to
impact problems in ways that make debugging impossible vesus WinDBG. That
along with the fact that I prefer a GUI interface, has caused me to swear
off SoftIce when possible.

I poked into my desktop machine a firewire adapter, and use as a second
machine my laptop, through it’s built-in
firewire. The interface was sold with cables, and I bought an auxiliary
null-modem cable for debugging > XP targets
for several dollars. Windbg works ok now. Im pretty satisfied with this
debugging set-up.

Hi,
VirtualPC 2004 does allow two-machine debugging on a single machine just
like VMWare. In my limited experience it seems slightly more development
friendly, mostly in that it doesn’t eat the CPU whole while sitting on a
breakpoint, which probably improves debugging performance.
It should be noted that there are serious advantages to using a virtual
machine getup to debug software as opposed to one or more physical
hosts, particularily for FSDs and filters. Among the bigger advantages
are the fact that you can maintain multiple different OS-en and other
setups on a single physical host. All it costs you is disk space, 1-2
Gig suffices for a basic OS setup with a couple of apps. If you have the
hardware to support it - mainly RAM - you can even run two or more
virtual machines simultaneously on a single host.
Another big advantage is that both VMWare and VirtualPC support undoable
file systems (probably by maintaining a block-level delta of the disk
image), which means that if you screw up your file system, all you need
to do is to discard the changes from the session.
VMWare also supports snapshotting, which allows you to persist the full
state of the machine at some point in time. This can come in handy to
replay a sequence of code or events repediately, while homing in on the
source of a problem.
The disadvantage for FSD & filter work, I suppose, is that the virtual
hardware is fixed, so you’re not going to have much variety in the
storage stack and below.

Indeed, I think you could build a dual processor Opteron system for about the same price as VMWare ESX - and then you would have both 32 and 64 bit MP configurations covered!)
Log structured disks are a nice feature, particularly the ability to “roll back” to an earlier machine state. Of course, you can achieve something “comparable” with existing Windows software (e.g., volume snapshots) although certainly far less trivially used.

I used to work with SoftICE a long time back. But switched to VMWare/WinDbg combo a few years ago and its has been working fine for me. WinDbg has gone consistantly better, atleast wrt the way I use it.
One painfull thing about windbg over serial port is the speed, it can be very bad.
Has anyone used the firewire support of WinDbg?

The time it takes to boot a VMWare (Or VPC as well) machine is far from rational
for me.
I’m sticking to separate debugging machines using SoftICE, until I can get a
cable:-)

I’d never think of looking for Staples in Germany… nice idea!

XP on VMWare doesn’t take THAT long to boot, in my experience (though it
certainly could be improved). As I’ve reported before, VMWare works
well with WinDbg as long as you are aware of the limitations (for
example, in my case I needed to install a virtual serial port emulator
to get it hooked up, and furthermore I’m not able to debug user-mode
code in NT4 on a VMWare for some reason). SoftIce does work natively in
a VMWare, which is a pretty amazing achievement in my opinion.
Having just accepted a job offer at VMWare, I will soon be able to look
into these issue personally. 
Better debugging support may result in
greater Workstation sales not just to individual developers, but to
entire QA teams, when it becomes clear to developers how easy it can be
just to snag a particular QA image to debug a reproducible problem.

Easily sold in Moscow on any computer marketplace. Just ask for “null modem”.

IMHO, but VMWare is by far better money investment then SoftICE.

> VirtualPC 2004 does allow two-machine debugging on a single machine just
like VMWare. In my limited experience it seems slightly more development
VirtualPC is more buggy then VMWare, at least on ancient DOS games which use
flat realmode. It hangs sometimes. VMWare - practically never.
Never tried VPC with NT in it - no goal, the debugger is not connectable
anyway.

I have a dual processor system with 2 gig of RAM. VMWare boots far faster
than the real hardware on my system.
