Hello Hans.
There is a tracker at http://sourceforge.net/projects/dosemu , I
don't know if any DOSEmu developer reads this list so maybe it is more
effective to use the tracker there (or maybe not...).
Thanks!!!
Bye.

Hello DOSEMU team,
I could not find where to report bugs, so I hope this is a valid way.
It seems that DOSEMU does not support newer CPU's. Maybe simply, because
it was not updated since they arrived. I've checked the SVN version at
http://dosemu.svn.sourceforge.net/viewvc/dosemu/trunk/src/base/init/
My /proc/cpuinfo says:
vendor_id : AuthenticAMD
cpu family : 16
model : 2
model name : AMD Phenom(tm) 9550 Quad-Core Processor
The
switch (get_proc_intvalue_by_key(
kernel_version_code > 0x20100+74 ? "cpu family" : "cpu" )) {
in src/base/init/config.c tests for values 5, 6, 586, 686, 15.
The result is that config.cpu_spd is zero, which causes a "Division by
zero" on booting dos.
If you run dosemu with options
-h0 -O
it dumps the configuration to stderr.
It dumps (among a lot else):
CPUclock infMHz
That is a (poorly formatted) "infinity" result of the division:
(((double)LLF_US)/config.cpu_spd)
in src/base/init/config.c
Adding a case 16 to the switch statement solves this. It reports the CPU
speed as 2210.17 MHz
It also makes my DOSEMU boot. I'm not sure whether it's completely OK, yet.
See the attached patch to the 1.4.0 version.
There are more newer processors around. Here's number 17 in this Ubuntu
