Syslinux - Nov 2003 - Format problem in previous mail. RE: Closer with pxeboot, but n ot all there...

Hi again... 
	The text under "BTX loader..." should appear as a block where each
line is 56 characters long.  "BTX halted" is on its own line.  
	Apologies for my mailer...

Subject: Closer with pxeboot, but not all there... 

Hello... 
	With syslinux pre7, I am consistently getting what looks like a
stack dump out of the FreeBSD loader. 
	I have seen this behavior from pxeboot before.  Maybe once out of
every fifty or so runs of pxeboot, I would see an error message like the one
below, but it was both rare and inconsistent.  Now I am getting this message
every time pxelinux invokes pxeboot: 

BTX loader 1.00 BTX version is 1.01

int=0000000d  err=000000b8  efl=00010246  eip=0000e306
eax=00000000  ebx=00000000  ecx=00000000  edx=00084fa0
esi=00000000  edi=00000000  ebp=00083ff8  esp=00083ff0 
cs=002b   ds=0033   es=0033   fs=0033 gs=0033  ss=0033
cs:eip=07 80 20 00 07 80 20 00-07 80 20 00 07 80 20 00
ss:esp=b8 00 00 00 00 00 00 00-00 00 00 00 16 00 00 00
BTX halted

	The message is consistent-- that is, pxeboot displays the same
message every time it is invoked from pxelinux.  
	I hope this helps, let me know if there's anything more I can tell
you. 
	-Chris

Okay... that's a useful piece of info.

Bother.  Unfortunately this dump doesn't make munch sense to me, for 
obvious reasons; I think we need to try to involve the pxeboot maintainer.
