I am currently trying to develop a pci card/driver. Currently I have gotten the card and driver to work on an older machine with the following specs.

root@localhost TestCode]# cat /proc/cpuinfo

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 11
model name : Intel(R) Celeron(TM) CPU 1200MHz
stepping : 1
cpu MHz : 1196.927
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 mmx fxsr sse
bogomips : 2394.96
clflush size : 32

However when I try to plug my board into a newer machine with the following specs....

[root@localhost bramsey]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Celeron(R) CPU 2.93GHz
stepping : 9
cpu MHz : 2933.536
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 5
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx
lm constant_tsc up pni monitor ds_cpl tm2 cid cx16 xtpr lahf_lm
bogomips : 5870.73
clflush size : 64

The system will not boot. It freezes at the splash screen for the BIOS. Any ideas on how to trouble shoot this issue would be great. Thanks.

well if it's freezing at POST that's prior to the driver loading.

I would recommend getting a POST card to find out where in the boot sequence the system is halting. Might provide you some insight to the problem with the hardware.
