[9fans] Win2k-NTFS and plan9, dual boot

[Steve Simon]

Ok, I'am being foolish but I cannot see where.
I reinstalled my laptop with Win2k with NTFS.
So I manually added a line to boot.ini:

	c:\bootsect.p9 = "Plan 9 from Bell Labs"

and build a bootsect.p9:

	touch /tmp/diskimg
	disk/format -b /386/pbslba /tmp/diskimg
	dd -bs 512 -count 1 < /tmp/diskimg > bootsect.p9
	rm -f /tmp/diskimg

However when I try to boot plan9 I get:

	Loading Plan9
	PBS ... Bad format or I/O error
	Press a key to reboot

What did I miss?

Last I knew, the NT boot loader didn't let you have
references to files on NTFS in your boot.ini.

You could use smart boot manager instead:

disk/mbr -m /n/sources/contrib/rsc/mbr.bootmgr /dev/sdC0/data

Seems that it does.  I've been using it for a considerable length of time.

I've got a Windows XP system with 15G NTFS partition followed by 5G
plan9, it boots into Plan9 via the Windows boot.ini menu with
C:\bootsect.p9 being created via

dd -bs 512 -count 1 -if  /dev/sdC0/plan9 -of  bootsect.p9

(Machine currently has other problems, the changes in 9load circa Dec
2004 seem to have stopped 9load working, but this is unrelated to the
Windows boot menu)

Oddly, in one incarnation of my laptop this worked, in the next it
resulted in Windows booting, plan 9 booting, then either Windows or the
bootmgr complaining that the disk was corrupt and requiring a reinstall.
