NuMega Driver Studio...

NTDEV

DriverStudio 1.0 is ancient. The current version is 2.5, and a 2.6 will be
coming out soon. You get BoundsChecker for Win98 with it.

Do you mean that the device vendor must supply an
OS-independent kernel debugger for them?
Something like Sun’s “Stop-A” or old LSI-11 stuff - the
keyboard hit which breaks the machine out of the OS to the
ROM monitor (with
the ability of continuing the OS - yes, even as complex as
UNIX - after this). Good idea.
Too bad PCs have no such. And they could. The CPU’s System
Management Mode can be used for this.

We are going into places I cannot speak authoritatively about. I’ve assumed
that SoftIce, or any kernel level debugger, creates a virtual machine that
the OS runs on top of. Therefore, when the OS is stopped at a breakpoint
the virtual machine can still proceed with its work (debugging). So the
device vendors don’t have to provide such a tool because the generic Intel
PC machine is common to Dell, Compaq,… and SoftIce supports all. The
virtual machine is OS-independent and provides instruction level debugging.
If we want to do symbolic debugging beyond this then the debugger becomes
enhanced and OS-aware.

If this is true, then you can see why a GUI running on win32 is not ideal
for this virtual machine. The OS gets halted, this halts win32 support, the
GUI gets halted, now you can’t use the GUI.

I qualify everything I just wrote with the acknowledgement that I’m not a
debugger developer and I don’t play one on TV.

Last time I looked (more than a year ago), SoftICE doesn’t create a virtual
machine in any sense that I’d understand. With a true VM, the dependent OS might
choke but one could still use the VM. For example, zap a random value into the
GDTR or IDTR and see what happens. No, SoftICE was pretty dependent on the
software-cum-hardware structures the OS had set up.

See? I knew I should have kept quite. No, actually I’m always glad to
learn something.

Thanks James.
