[syslinux] Linux syslinux-3.72 does not update boot block for SD devices

[Jim Fridlund]

I see what you mean. I stepped through it with the debugger and I see  
syslinux trying to write to the mbr by invoking xpwrite() function  
which calls the pwrite() system call. The system call returned 512  
bytes, but reading back still showed the old values. Again, thanks for  
the help!
