Syslinux - Jan 2002 - Boots from prompt but not from syslinux.cfg

Hi,

I have a problem with syslinux.cfg.  I can boot successfully by typing
on the boot: prompt but not from an entry in syslinux.cfg.

The command line is 
boot: vmlinuz initrd=dvzip1.img root=/dev/ram ramdisk_size=8192<enter>

However if I enter the label of the kernel to boot, it fails to run
/sbin/init and in its absence /sbin/sh.  The kernel boots correctly but
gets stuck after the following messages, after which I have to do a hard
reboot.

autodetecting RAID arrays
autorun ...
... autorun DONE.
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 64k freed

Could it be that the kernel command line is not formed correctly?  Is
there a way to print out the kernel command line.

I am trying to create a bootable Iomega Zip disk using an internal Zip
drive.  After some experimenting, I managed to boot off the disk but am
getting stuck at what is probably the last step.

Thanks in advance.
CheeChun

There was some problem with a trailing space at the end of the
commandline. Maybe this hits you?

You could patch the kernel, if you get it to boot it's in
/proc/cmdline.

Dumb question: could you please make sure the last line of your 
syslinux.cfg ends with a newline?
