EPIA M 600 / Samuel 2 settings & errors

I have a epia m via c3 chip mobo samuel 2 600mhz
on which im trying to install gentoo 2005.0

my current make.conf looks like this
CFLAGS="-Os -march=i586 -fomit-frame-pointer -msse -mmmx -mfpmath=sse -pipe"
CHOST="i586-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
ALSA_CARDS="via82xx"
VIDEO_CARDS="cle266"

(no x kde etc it will be a simple server)
my stage3 was an i686 (im trying the x86 at the moment)
(im installing direct from stage3)

the kernel is gentoo sources with no framebuff or boot logo
& has the cpu set to viac3

the problem is after syslog-ng is installed if i try to start it
i get illegal instruction

This is getting really annoying, I need to move data off an existing small server
on to this one & i cant get past this error

did a search on the forums & the wiki & i think my settings are correct
if anyone can paste their make.conf for the 600 board & help me with syslog-ng
id really appreciate it

I'm pretty sure the Samuel 2 is only i586 compatible, so you can't start with an i686 stage tarball.

i redid the install with an x86 tarball with the exact same error
gave up on syslog & tried metalog & got the same error..

do i have to go thru a full stage1 install ?

Try without -msse !!!!
Samuel2 has no sse support !

I have a MII 6000 board and i am wondering about the cflags and stuff as well.

I will try to find out something about on the internet, but maybe someone has an answer here.

I always used i586 layout, until i heard the C3 is an i686, but is missing the CMOV feature. Gcc thinks all i686 feature it, so it could result in broken code. I didn't care too much and reemerged gcc and everything for the i686 environment. Since then, i am compiling happily without broken code. BUT my cflags look like this at the moment:

When in doubt check the safe cflags list: http://gentoo-wiki.com/Safe_Cflags#Nehemiah_.28Via.29

I think this board is an Ezra (VIA Samuel 2), but that is listed directly below your link, so thanks anyway.

But i had these safe flags running from the beginning and i am curious if i686 works now and the cmov issue is resolved. And i am curious if -march=c3 uses i386 for all packages. I will do some reading about it this evening.

btw, is this too far offtopic for the "gentoo installation" forum?

I have an epia-v 800MHz. I just did a 2005.1-r1 stage 3 (x86) install. I went with a CHOST setting of i586-pc-linux-gnu. My CFLAGS are -march=i586, -m3dnow, -03, -pipe, -fomit-frame-pointer. After configuring my bootloader, I rebooted the machine. Somewhat to my surprise, I am not at the login prompt. I am unable to enter any text. Do you think this is a problem with not adding support for the keyboard in my kernel or something else related to CHOST or CFLAGS?

Did you take a stage3 tarball for i686?
Otherwise i think you flags are ok for that board, if your system is compiled wiith them.

And to answer my questions from from above: march=c3 compiles for i486.

My board died recently but it was a 800mhz samuel 2 and was a i586. Take the mmx and such out of your CFLAGS. CFLAGS="march=i586 -Os -fomit-frame-pointer -pipe" worked the best for me. You can add mmx and such to your make.conf USE settings, the best place for them.

Do I have to install using a stage 1 install? Like I said, I did a stage three install, the sytem rebooted fine and went to the login prompt. I just can't use my keyboard or mouse. Is the fix as simple as enabling something in my kernel and rebooting... Or again... do I have to do a stage 1 install?

No you dont have to do a stage1. You probably have a miss configuration of your kernel. You can reboot with a livecd, remount your partions, proc swap, chroot, env-update and source profile. "cd /usr/src/linux " and the make menuconfig go to Input device support ---> and keyboard and mouse stuff. Then remaek your kernel. and reboot.

Check out this link: http://gcc.gnu.org/ml/gcc-patches/2004-07/msg02718.html

This is a patch for gcc which sets the architecture to i686 and masks out the CMOV instruction when -march=c3 is selected. I tried this some time ago and it did work for me. I had to do a stage 1 install and patch gcc...
