Hi, Michael,

I have followed your suggestion to unable the CONSOLE_SYSLOG option. To 
enable this option, I have to update ipxe to the latest version. From then 
on, I got a surprise present. It did not hanged at "Couldn't open drive
multi(0)disk(0)rdisk(0)partition(1)/NTLDR couldn't open drive 
multi(0)disk(0)rdisk(0)partition(1)" anymore and seemed to enter NTDETECT 
phase. However, I still can't see windows xp logo because of NB reset 
somehow happened.

I also captured the trace of whole booting process by wireshark and attached 
it in mail. It already contained the syslog inside. From the wireshark log, 
there has some error messages about INT 13 driver 80. Could you please give 
me some suggestions about the next step? Thanks very much!
