[SOLVED] Syslinux : Missing OS

Question

Hello
On booting, Syslinux show me this error message : `Missing OS`
After, the BIOS displays its `Operating System not found` error message.
Syslinux is is properly installed (MBR right, /boot (/dev/sda1) is flagged bootable, with Syslinux on it, all this tested with HDT).
I have NOT a GPT :
# fdisk -l
Disk /dev/sda: 60.0 GB, 60022480896 bytes, 117231408 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sda1 * 63 64259 32098+ 83 Linux

/dev/sda3 3968055 117231407 56631676+ 83 Linux
Disk /dev/mapper/arch_root-image: 1490 MB, 1490026496 bytes, 2910208 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
`syslinux-install_update -im` worked well.
I have a Phoenix BIOS.
Thanks for your help

Done, but nothing more.
Here is my syslinux.cfg
# Config file for Syslinux -
# /boot/syslinux/syslinux.cfg
# Comboot modules:
# * menu.c32 - provides a text menu
# * vesamenu.c32 - provides a graphical menu
# * chain.c32 - chainload MBRs, partition boot sectors, Windows bootloaders
# * hdt.c32 - hardware detection tool
# * reboot.c32 - reboots the system
# To Use: Copy the respective files from /usr/lib/syslinux to /boot/syslinux.
# If /usr and /boot are on the same file system, symlink the files instead
# of copying them.
# If you do not use a menu, a 'boot:' prompt will be shown and the system
# will boot automatically after 5 seconds.
# Please review the wiki: https://wiki.archlinux.org/index.php/Syslinux
# The wiki provides further configuration examples
DEFAULT arch
PROMPT 0 # Set to 1 if you always want to display the boot: prompt
TIMEOUT 50
# You can create syslinux keymaps with the keytab-lilo tool

# Menu Configuration
# Either menu.c32 or vesamenu32.c32 must be copied to /boot/syslinux
