[syslinux] Unable to boot my USB flash drive, even with USB-ZIP trick...
I've been using a USB flash drive for quite a while now, and in my previous system it worked great, but, I find with my new motherboard now that I have upgraded I can't boot it. So I decided to try the trick mentioned in the README.usbkey file where you make a ZIP drive like image on the flash drive and set the BIOS to boot a USB ZIP drive instead. Unfortunately, it still doesn't work. It never even says Booting USB-ZIP or something (when it's booting a CD-ROM, it says "Booting CDROM" while it loads.) Probably the most curious thing about this situation though, is the fact that the BIOS explicitely SAYS that it has found a USB storage device! In the information it shows on the top of the screen just after the initial POST testing and just before it starts to actually boot, I see text informing me that it has recognized my USB storage device. It does not show ANY information on any other USB devices such as my printer, which say to me that it's not simply informing me of all USB devices it sees, but, specifically pointing out that it actually recognizes that particular device for what it is. In case it's related, this is the mkdiskimage command line I used to the best of my memory: mkdiskimage -4 /dev/sda 239 64 32 I used 239 cylinders even though I have a 256MB device just in the hopes that maybe it will increase compatibility on some weirder systems out there by some maybe 1%, but, it probably does nothing. Still, I'm strapped for space, but, I can still afford to give up <6MB just in that vague possibility it will be more likely that more systems will accept the drive. I keep diagnostic tools and such on this flash drive to help me diagnose and fix problems -- which is part of why I need to get it bootable again...

Btw, have you enabled the USB keyboard in BIOS? With my award bios, usb key won't boot it is not enabled. What does it do when you boot on a USB key? "no bootable partition found" or another message? Have you trouble only with one specific USB key or have you tried with another one?
