Never mind, got it working, turns out there were some issues with QEMU and large linux kernels. Will have an howto soon for my dual boot config

Greetings folks,
I am trying to make a bootable USB installation, which can also be loaded by Qemu from windows. (Helps in situations like my windows PC which dosnt boot a liveusb).
Progress:
I modified linuxrc script to mount /dev/hda as /cdrom. Qemu loads KNOPPIX/knoppix as /dev/hda. With the new minirt.gz I am tried booting from USB, works as expected.
For the Qemu case, I am getting some problems.
my batch file contains this:
qemu\qemu.exe -L qemu/ -no-kqemu -m 512 -kernel linux -initrd minirt.gz -hda KNOPPIX/knoppix -append "qemu root=/dev/hda ramdisk_size=100000 init=/etc/init lang=us toram knoppix_name=knoppix knoppix_dir=knoppix BOOT_IMAGE=expert nomce apm=power-off vga=791"
The errors I am getting are this:
RAMDISK: Couldn't find valid RAM disk image starting at 0.
VFS: Mounted root (iso9660 filesystem) readonly
...
/etc/rcS.d/S00knoppix-autoconfig: line 100: /proc/sys/kernel/printk: No such file or directory
and bunch of errors.
I think something went wrong while loading the Ramdisk, also I dont see any of the prints from minirt.gz
Isnt root=/dev/hda sufficient for ?
Any suggestions would be great.
Thanks,
LS

I am very interested in a usb flash drive that will be both bootable on metal as well and qemu bootable. I believe Qemu-puppy is doing this here:
http://www.erikveen.dds.nl/qemupuppy/
To be even more demanding, I have found it possible to run the same image in and Mac OSX Q (emu) application.
Let's add one more request-- an encrypted root filesystem, with /boot in the clear. Feraga.com has a project for this
Any interest?
DSL (Damnsmalllinux) has a way to do the "real" bootable USB + qemu bootable USB. I believe it is called the "5-way install".Originally Posted by fellow
Once it is installed on the USB key, you can boot in multiple ways:
1) Directly from the USB device.
2) For computers with no USB boot support, boots from a mini-CD or full-CD disk and then starts DSL from the USB key.
3) For computers with no USB or CD boot support, boots from a floppy disk and then starts DSL from the USB key.
4) Boots inside QEMU from a computer running Windows host operating system.
5) Boots inside QEMU from a computer running a Linux host operating system (Red Hat, Ubuntu, etc).
and someone in the user forums also added a MAC version of QEMU so you could boot it from a computer running a Macintosh operating system.
