[syslinux] Returning to syslinux bootloader

[Dag Wieers]

Hi,

I was wondering whether it is technically possible to go back from eg. DOS 
or Linux directly to the bootloader (instead of rebooting the hardware).

We currently have 2 images (one DOS and one Linux) that need to be started 
before loading a system. They do things like disable PXE on NICs (using an 
Intel DOS tool), verify the correctness of the network patchings and 
validate if the hardware was configured according to corporate standards 
(usage of PCI slots, hardware revisions and firmware).

But rebooting the hardware on certain devices takes a long time, if we 
could go back to the bootloader it could be useful. Even when the hardware 
may not be properly reset.

I noticed that HDT can exit and return to the bootloader without a reboot, 
the same could be useful for memtest and some other tools that are not 
com32 modules.
