Re: problem with pxe grub

hi
thanks for your prompt answer.


this is the header of our kernel. (btw: it is 2.2.19, and for the moment we
cannot upgrade since the sw we have to run on our farm relays on it :-(((()

00001f1:  0701 0037 c500 0000 00ff   ff01   0355 aaeb   ...7.........U..
0000201: 2448 6472 5301 0200 0000 0000 107f  0300  $HdrS...........
0000211: 0100 8000 0010 0000 0000 0000 0000 00d3  ................
0000221: 0320 90e8 11b8 0015  b281 cd13 8cc8 8e      . .............

this is the result of displaymem operation from the grub prompt:

eisa memory bios int is present
address map bios int is present
lower mem:566K, Upper mem (to first chipset hole): 2096048k
