I'm building a new machine based around an Athlon 1700XP and an Asus
motherboard with a VIA chipset, (VIA VT8364A Northbridge and VIA
VT686B Southbridge), and 256 MB of RAM.
I've noticed a couple of, (quite possibly unrelated problems):
* Misdetection of an Athlon 1700XP as a Duron
* Data corruption reading from an IDE CD-ROM
I originally booted 2.4.18, and noticed that /proc/cpuinfo was
detecting the CPU as a 1104.392 Mhz Duron.
Ignored that for the time being, and started copying the kernel source
from a CD-ROM.
Decompressing it gave a CRC error, so I tried booting with mem=64M,
and got the same problem.
The CD-ROM drive and disc work fine on a Duron 650-based Linux box, so
I reduced the CD-ROM to 12x speed using hdparm, and managed to copy
the kernel source across successfully.
Booted 2.4.19-pre5, and /proc/cpuinfo is still wrong. Likewise for
2.5.64.
Any suggestions?

This string is set by the BIOS at power-on time.
If it really is an Athlon, your BIOS is horked.
Try upgrading it.
Out of curiosity, what does x86info[1] make of it ?

The story behind this machine is that I was building it as cheaply as
possible for my parents, (just to browse the web, and write E-Mail).
I never use pre-assembled hardware, prefering to build my boxes from
scratch, but I broke that rule to save money, and recommended that
they bought a pre-assembled case, motherboard, ram and cpu.
To cut a long story short, the board was jumpered for 100 instead of
133, and when re-jumpered at 133, it crashes during init.
It's being returned tomorrow, and from now on, I build systems from
scratch. Always.
