= This is a transcript of the boot messages on a 735 using the default
= CVS config:
= 
= kernel(0x0000001), 0x04DFF870, 0x04DFF900, 0x00016A70)
= Clear BSS 0x00118470-->0x0012FA80
= Boot loader: HP-UX ISL
= Warning realmode_setup.c *guessing* where free mem starts!
= realmode_setup exiting.
= 
= This is better than yesterday when there was no output.  The BSS
= region looks ok.  HP-UX ISL is correct.  The address of _end in the
= vmlinux object looks reasonable:
= 
= _end                |0xc012fa80|extern|data   |$DLT$
= 
= Why does realmode_setup have to guess where free mem starts?

The _end symbol is not a reliable indicator of where
the kernel's memory ends.  And the hpux
bootloader doesn't provide the SOM header from whence this could
theoretically be calculated.  I haven't tried out the _end trick
posted last week, but it looks like it'll work (don't call the symbol
_end if you try it).  As long as your kernel links, the guess is
probably OK for now.
