I have no problems in releasing the source code. I am not maintaining it anymore, so if someone wants to keep working on it, here is where I uploaded the source code: http://www.reblusoft.com/ubusb/ubusb_source.zip I have only managed to compile it in a Linux box. I have modified also the menu syste...

Well, you got the syslinux prompt when booting with the Key formatted as HDD. You could try changing the FAT type in that instance. Another option is removing the -Z in the makebootfat line of the ubcd2usbmul script so that the multiboot would be both USB-HDD and USB-FDD, but not USB-ZIP. RMD-FDD, s...

Well, that's bad... There is only one more thing I can think of... Syslinux was able to boot in your laptop but it was not able to see any partition...maybe there is some kind of problem with LBA support... since your Key has 2GB, it does not really require LBA (only if >8GB) so you should be able t...

Maybe the best solution would be to use the multiboot option of makebootfat. I have updated my package with an additional ubcd2usbmul file that creates that type of geometry. Its usage is the same as its companions: ubcd2usbmul h: f:. Note that you do not have to wait until the whole UBCD is copied ...

In order to clarify a little bit the problems with USB booting, let's look at the 3 basic modes of formatting a USB Key, using my own key as an example :wink: The main difference is in the partition table. A USB-FDD formatted key does not have one. We just see garbage: USB-FDD http://img291.imagesha...

The contents of the USB Key look fine to me. You actually have ubusb.c32 in there and syslinux.cfg. If you get that boot prompt, it means that your computer is actually booting from the Key and finding the bootmanager, which is syslinux, but for some reason the syslinux is not finding its configurat...

I believe that from Windows you checked that there was some content in the USB Key... I have some suggestions for your laptop: 1.- Try typing ubusb.c32 at boot prompt 2.- Check that the contents of the ubcdroot subfolder of Erwin's package are actually in the USBKey. For your destop, 1.- You might w...

They specifically say Please note that FreeDos has some problems booting from USB. It works only on very few conditions. But they do not give further explanations. The example they give actually has the following additional parameters -E 255 \ -Z \ -m mbrfat.bin -F \ You can try... I'll double check...

For FreeDos support, try adding -E 255 to the makebootfat line: -E, --drive DRIVE Set the BIOS drive to setup in the FAT boot sector. Generally this value is ignored by boot sectors, with the exception of the FAT12 and FAT16 FreeDOS boot sectors that require the correct value or the value 255 to for...

By the way, NwDsk, here are some suggestions for your nice batch program: - Add freedos.img, grub.iso and offline.iso to your exclude file list. The first one will be overwritten anyway, but this would save the time of copying it from the CD. - Add Insert to your folder exclude list for now, until w...

Not to worry. If you have WinXP you can go to the Control Panel- Administrative Tools- Computer Management - Disk management and right mouse click on the F: drive (your USB Key) and reformat it.

What model is that USB key? By the way after running makebootfat, you should have something in the USB key, at least the file ldlinux.sys... Is the drive empty?

According to the guys at makebootfat, by using the -Y option you overcome the 1GB limitation: Enforce the syslinux 3.xx FAT support. Syslinux 3.00 supports all the FAT types and sizes but it requires a special customisation of the boot sector and of the file `ldlinux.sys'. This option does this cust...

I actually tested it with a Flash Drive, aka USB key (a Cruzer Micro 256MB, to be specific). I also did some minor testing with a Compact Flash connected to a card reader. So I guess anything under 1GB connected to an USB port should work. Syslinux has the limitation of the 1GB limit. I also think i...

1. What is the possibility we could make ubusb.c32 run on CDShell? I was thinking, if we could get a single menuing system to run across both CD and USB, then we could have a unifiied release. Furthermore, if we could hide non-working entries on specific devices (eg. hide Windiag when UBCD boots fr...

Ok I think I am ready to explain how to create the Ultimate UBCD on a USB drive, despite the lack of interest in the poll (there are only 5 votes). Still, this thread seems to have quite a few views... I hope this is not a long post. I’ll call the package the UBUSB. The instructions are basically fo...

Thanks! It works perfectly.

By the way, I am testing the menu with bochs and the combination memdisk and windiag.img actually works in the virtual machine! So it seems to be BIOS dependent.
