...he system loads from). The requirement is to have a duplication of the Linux Image, and that syslinux should calculate CRC of "the first image" (say bzImage_1). If the CRC is correct then load the image, if the CRC is not correct, than syslinux should try "the other image" (say bzImage_2). If even that is no good do nothing. Any suggestions as to how to implement the requirement ? Thanks Mau

A custom COM32 module. Look at ifcpu.c32 for an example of an if-else module and the crypto functions in com32/util/ -- -Gene

You should be able to implement this logic via the embedded Lua interpreter. I don't know whether the performance would be acceptable, though (at least without resorting to C coding)....

Hi, I am using qemu for testing new versions of syslinux before installing on an embedded computer. Everything works fine under qemu (1.5.0), so I updated extlinux from 4.06 to 5.11-pre3 on the computer. I found that the autostart's timeout does not work. The timeout value is correct but nothing happens. It worked well with extlinux 4.06... I tried with extlinux 5.01, 5.10, 5.11-pre3 and
