Hi, I am trying to use MEMDISK from the GRUB boot loader, and gets stuck on the memory detection. MEMDISK reports dos_mem = 0 low_mem = 0 high_mem = 0

.../git.zytor.com/users/genec/syslinux.git Branch memdisk-maxmem-for-hpa This is a preliminary hack to introduce a new option that will allow an end-user to limit the amount of available RAM as returned by any call that MEMDISK touches. This works by adding additional memory reservation(s) (through insertrange()) to reserve the memory between the specified address and the top of RAM. For now, the parameter is int15maxres (implement INT15h MAX by reservation) and is specified in bytes. I welcome feedback on its functionality, default unit (ie 1 byte versus 1024 bytes or even unit of 1024 bytes but must...
