Hi David
i can boot automatically using two method:
* First method:
o special ELAN kernel variant
o edit initrd.lrp /boot/etc/modules to append a "pata_legacy"
line (nothing else)
o devices are automaticaly created by "mdev"
* Second Method (preferred because there is not editing in
initrd.lrp package)
o special ELAN kernel variant
o edit syslinux.cfg, adding a "KMODULES=pata_legacy" on the
"DEFAULT" line (see the follow syslinux.cfg sample)
o device are automatically created by "mdev" during boot process
A last note: net4501 has three NS DP83816 network card, so you must load
the "natsemi" kernel modules to activate these nic cards (making a "Find
& load modules for hardware" discover the natsemi driver correctly)
I have booted correctly the system without "libata.dma=0" parameter, so
I think it is not necessary.
Thanks
Graziano
------ syslinux.cfg on my net4501 -------------
SERIAL 0 19200
DISPLAY syslinux.dpy
TIMEOUT 0
APPEND reboot=bios console=ttyS0,19200n8 VERBOSE=1
DEFAULT /syslinux/linux initrd=/initrd.lrp rw root=/dev/ram0
LEAFCFG=/dev/sda1:vfat KMODULES=pata_legacy
