H. Peter, three simple commits here[1] (for_hpa branch). Gert, sample binaries are here[2]. --- mdiskchk: Add --no-sequential mode It might be useful to suppress MDISKCHK.COM's classic behaviour of probing all BIOS drive numbers in search of MEMDISKs. Some BIOSes might not enjoy being probed. --- memdisk: Correct El Torito termination response Two changes to the INT 0x13, AH=0x7B El Torito function: 1. Support the DL=0x7F "terminate all" parameter 2. Only respond to DL=0x7F or DL=our particular emulated drive number This prevents tools like Bart Lagerweij's El Torito tools from receiving false positives when probing all drive numbers. --- eltorito: Include drive 0xFF in scan Although drive 0xFF could yield a false positive as the El Torito booted-from drive number, some users of GRUB4DOS actually use this drive number, so we should include it in our scan. --- - Shao Miller [1] http://git.zytor.com/?p=users/sha0/syslinux.git;a=shortlog;h=refs/heads/ for_hpa [2] http://git.zytor.com/?p=users/sha0/syslinux.git;a=commitdiff;h=cdeaadbf3 9f0292ff2936c1a0a9dc7c13c10bced
