It points back at ourselves, anyway, and we end up doing, in the end, the same thing as the safeint stub would do. Furthermore, the test was broken for years, and so this is actually closer to what we originally tested. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

Support "extended attributes" for INT 15h, AX=E820h 2008-10-13T19:26:58+00:00 H.

F*cking morons. Implement handling of extended attributes in: - e820 parsing in the core - e820 parsing in libcom32 - e820 parsing *and proxying* in memdisk The latter is the really painful one.

memdisk: install a DPT if needed in INT 1Eh; better zero-drive detection 2008-07-03T22:22:39+00:00 H. Peter Anvin hpa@zytor.com 2008-07-03T22:22:39+00:00 8e5db045c60ce25a9eb65a1803d47be4002a3e17 Per the Interrupt list, treat INT 13 08 returning with CL=0 as a failure, meaning single drive only. If we find ourselves the only floppy drive, install a DPT into INT 1Eh. This appears to be needed for PC-DOS 7.0 to boot. This can be overridden with the "nodpt" option, and forced with the "dpt" option.

This is a pretty big hammer and is largely for debugging at this stage; it probably needs more polishing before it can be made official.

Hello all,

I ran across a couple bugs in memdisk concerning hd images the other
day.  With the attached patch I've been able to successfully boot a
32MB gzipped hd image.  (I'll put the image up for a short while at
ftp://ftp.io.com/pub/usr/duanev/fdoshd.img.gz)

The pxelinux.cfg entry I'm using is:

    label fdos
        kernel memdisk
        append keeppxe initrd=fdoshd.img.gz

syslinux/memdisk is great, thanks Peter et. al.!
