[gPXE] sanboot failed for intel motherboard - s3200sh

[Aclhk Aclhk]

i have install centos 5.4-64bit. I followed your instruction to install the diag MBR.

sanboot iscsi:192.168.1.1::::iscsi-gpxe
Registered as BIOS drive 0x80
Booting from BIOS drive 0x80
L D80 C3FF HFF S3F P1 O0000003F M0000 E00

the booting then stopped.

        after the following commands:

dhcp net0

set keep-san 1

sanboot iscsi:192.168.1.1::::iscsi-gpxe

        

the server will reboot or hang (booting from......)
      
    
  



What is installed on the SAN's MBR?  Which boot code or boot-loader? 
There is a diagnostic MBR available at
http://etherboot.org/share/sha0/mbr-diag.bin.  After and only after
you've backed up the current MBR, you can write these 440 bytes over
the first 440 bytes of your SAN's MBR, leaving the partition table
intact (the rest of the 512 bytes).  You could then see what happens.



# dd if=/path/to/san of=mbr_backup.bin count=1

# dd if=mbr-diag.bin of=/path/to/san bs=1 count=440 conv=notrunc

# echo Perform test

# echo Restore with

# dd if=mbr_backup of=/path/to/san conv=notrunc
