Victor,
I downloaded the release from your website. It was the latest one. Here's
what I found in the Makefile:
VERSION = 3.0
# for the 3.0 final, set PRERELEASE to 100
PRERELEASE = 100
I am running this on a 650 MHz Pentium III:
% cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 8
model name : Pentium III (Coppermine)
stepping : 3
cpu MHz : 654.588
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 3
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36
psn mmx fxsr xmm
bogomips : 1307.44
% uname -a
Linux smtdbe 2.2.18-rtl #6 SMP Wed May 2 14:58:37 MST 2001 i686 unknown
Hope this answers you questions.
Thanks,
Tom
