USB Bootable memory stick for a proprietary Suse 10 platform

Hi there

I am a newbie in this area - I wonder if anybody can point me in the right direction. I am installing IBM Lotus foundations start (suse 10 linux distro) on a server without a cd rom drive and traditionally I have used an .iso image.

Instead I would like to boot up from a usb memory stick. I have tried using unetbootin to convert the image onto the usb stick. Although the server recognises the memory stick and initial boot up sequence, it does not load the linux files.

I presume some fairly simple config changes need to be made but I am not technical in this area. Are there any specialists out there who could help?

Many thanks
Jon
