Yes.  Back in the bad old days some folk wrote DOS programs that polled 
for input in a loop instead of using interupts.  This resulted in 100% 
CPU usage.  The fix is to go into the DOS Settings and set IDLE_SECONDS 
to 2 and IDLE_SENSITIVITY to 1.  You might need to use different values 
but those worked for me on a single CPU.  They work on my T60 but I have 
just got duo working and haven't worried about that yet.

You say you got a window.  I haven't been able to get my DOS programs to 
work in a window.  They want full screen.  Any suggestions?

I have just reinstalled RC4 on a Dell PowerEdge T105 server. After
upgrading to ACPI 3.7, and patching the Broadcom driver to support the
Dell chip, the system will finally boot in SMP mode. I use the /SMP
/APIC options for the ACPI driver.

I have discovered a couple of problems though. DOS and Win-OS/2 windows
don't work (haven't tried fullscreen yet). For DOS you get a window and
100% CPU use. If you close tye window, the CPU use drops down again. The
100% CPU is split across the two CPUs - it could be 50+50 or 40+60%.

Is this a known problem?

Another problem is that sysbench doesn't work. I get the "Please wait,
gathering information..." window, but the main window only shows up for
less than a second, and then closes.

Best regards,

I know about that - I have many of those programmes. I get the problem
on this system when I just try to open a DOS window however. I never get
a prompt - just the window.

Best regards,

On some systems, DOS won't work in APIC mode.
Some newer ATI video chips causes the same behaviour.

It is better to close your mouth, and look like a fool,

Change your USBMSD line to use 2 removables rather than 8 and SysBench
will function again.
