USB booting :: Motherboard Problem

Hi,

I´ve got Problems booting my USB-Stick with my elitegroup mainboard ECS-K7S5A. The stick is booting allright on other boards. There are several booting options in my bios:

USB-FDD
USB-HDD
USB-ZIP-Drive
USB-CDRom
USB-LS120

So far only USB-FDD finds my Stick, but stops with message: MISSING OPERATING SYSTEM. The other options are all ignoring the device. Here is what i have done so far:

Configuring the stick within DSL, booted from CDRom:
- Setting the drive geometry right (500 cyl, 5 heads, 32 sec/track)
- added the -s flag to the syslinux command within frugal_usb.sh
- tried the boot-0.8.img instead of the bootusb-0.8.img (cause USB-FDD was the only option my board seems to accept at all)
- tried another (working) usb device (a wrist watch :-)). Result: My windows partition was booted, despite i deleted all other boot devices in my bios. funny, but somehow strange

As mentioned above, the stick ist booting all right with an asus board of my friend (sorry, i don´t have the full description of it right here), plus: the stick of my friend isn´t booting on my board, which leads me to the conclusion, that my board is making trouble.

Any suggestions anyone??

Thanx,

lennart

I was never able to get the K7S5A or K7S5A PRO boards to boot my USB drive without using a boot floppy disk. I think the limitation is with the mother board, but have not been able to back this up because I have nothing else to test it on.
