Mkisofs Isolinux Image Checksum Error

I have a Mac Pro and am running Snow Leopard and Windows 7 Pro (64-bit). I'm attempting to flash a new graphics card, and so I have to be able to boot up the UBCD to a prompt. I've burned five CD's now and each and every one gives me the same message: "ISOLINUX 3.86 2010-04-01 ETCDisolinux: Image checksum error, sorry... Boot failed: press a key to retry..." I'm not sure what I'm doing wrong. I downloaded ubcd501.iso and am burning that to CD using MagicISO. I've tried burning at the slowest speed and at mode 1 and mode 2. I also downloaded md5sum and verified that everything matched, and it does. I should also note that I'm trying to add a few files in a folder called "Mac" to the iso (in MagicIso) before burning. Any help is greatly appreciated.

This is the problem. NEVER use an ISO editor for bootable CDs. Always create the iso again with mkisofs. You get the checksum error because the isolinux.bin (boot loader) file needs to be patched, so it knows its location on the ISO. This patching is done by adding the "-boot-info-table" parameter to mkisofs. Extract the UBCD501.iso to a dir named ubcd-extracted. Add your Mac folder in the ubcd-extracted dir. Open a command prompt and cd to ubcd-extracted. Run the following to generate the iso: Code:mkisofs -iso-level 4 -l -R -J -joliet-long -D -V "UBCD501" -o "../ubcd501-custum.is
