Dear MdeModulePkg maintainer,
Please find the attached patch that fixes El Torito format on media that do not have a 2KB block size. El Torito format can be used on different media (eg: USB). A ISO image can be dumped onto a USB mass-storage. These media might not have the same block size as the CDROM media (ie: 2KB). The El Torito code and the the El Torito catalogue assume a 2KB-LBA. In addition, the UEFI specification says in "12.3.4.4 CD-ROM and DVD-ROM": UEFI code does not assume a fixed block size. I was able to duplicate the issue by copying a debian ISO on a USB driver and try to open the device with UEFI.
