ntoskrnl issue on my Dell Latitude C610

[Steven Edwards]

Hi,
A little background info. I have a dell Latitude c610 with a P3m 1ghz CPU, 256Megs of Ram
and a 20
Gig hard disk. ATI Mobile Radeon Graphics chip with 16megs of Vram.

When I try to boot ReactOS the screen always go black after freeldr loads the drivers and
everything even if /NOGUIBOOT is selected and bootvid.sys is removed from the system. The
screen
never goes blue and the kernel never gets a point where HalDisplayString or the kernel
debugger
will work. I have added a function to my ke\main.c to manually write to the screen in text
mode
and have been using that to try to debug the boot process. The problem is that it never
consistantly crashes at one line of code. It always seems to be around a call to
KeLowerIrql but
depending on where I stick my debug statements it will change. Whats odd is that it will
fail 100%
of the time in the same place depending on where I move my debug statements. The only
thing I can
figure is that but writting to the display its interupting which is changing the failure
location.
The farthest in the boot process I can get is the call to KeLowerIrql that happens around
the
calls to SeInit1 and SeInit2.

Thanks
Steven

Hi,

can you add /MAXMEM=64 to freeldr.ini and try it again?

I forgot to mention I have tried with /MAXMEM=16 and I just tried with 64 and still no
change. I
have noticed a little discussion about users having this problem with FreeBSD and SMP and
APIC
enabled but this is a non-smp build and I don't see anywhere else we use APIC except
in the
multiboot if SMP is enabled. I have also tried ACPI and non-acpi builds with no change in
the
results. I will be picking up a Null modem cable tonight and will attempt to hook this
laptop to
my Linux box so others can view some of the debug output.

Thanks
Steven
