Brian, do you know why parted adds the boot code but fdisk does not? Maybe we should consider removing it? It's only use is to chain load the "active partition" boot loader. I can only think of three times this is going to be used: 1) Booting DOS/Windows: they have commands to add the boot code after the fact, and normally they would partition the disk first. 2) Booting with LILO installed to a partition: LILO had a switch to write the MBR boot code if you ever wanted to do this and anyone still uses LILO. 3) Booting with GRUB installed to a partition: GRUB strongly recommends installing to the MBR instead, and if you really must put it in a partition, and don't already have MBR boot code, you can use LILO to add it.

For my SoC the 0x00 address is one of potential places where bootloader binary is placed. The SoC considers this code valid if it finds data different than 0x00 or 0xFF. We normally store bootloader on FAT partition, not at fixed address in the SDcard. When it is not found on FAT partition, then LBA 0x0 is considered as next candidate. If we do have data different than 0x00000000 or 0xFFFFFFFF, then we will hang, not going to other boot options.

Hmm.... Nice to know :-) > If it > causes problems on a non-x86 system you should zero it out The problem is that we are using it with TI's SDK script to create bootable SD card. In this script we clean (write 0x00) the MBR before we run parted -s msdos. The problem is that parted itself (and silently) puts the code there and hence the embedded system thinks that there is a valid bootloader code and happily hangs. Is there any option to parted to avoid adding this code (and behave like fdisk)? > (or write > the system bootloader after partitioning). > The only fix I do see is to manually write 0x00 to the beginning of the MBR created by parted.
