Hi,
I'm trying to move a pxe multiboot test setup from
grub legacy to grub (2). One of the modules reads
another module, which is a plain text file. In my grub2
configuration, the open works, but the read returns zero data.
The working grub legacy configuration:
title foo exectest
kernel (nd)/386/bin/kpc32.elf U=0:115200 T=proc
module (nd)/386/bin/exectest boot
module (nd)/exectest.cfg boot.cfg
exectest is a test prog that opens and reads "boot/boot.cfg".
exectest.cfg is a plain text file.
The non-working grub2 version.
menuentry 'foo exectest' {
multiboot $kernel $kernel $kargs T=proc
module ${stuff}/exectest boot
module /exectest.cfg boot.cfg
}
exectest and the kernel are the same as in the grub legacy usage.
The kernel loads & runs. Other tests built into the kernel run.
exectest.cfg loads.
I can "cat exectest.cfg" from the grub command line, but not boot.cfg.
exectest loads and runs.
exectest OPENING 'boot/boot.cfg' works.
It gives an error if I map it to the wrong place or don't load the
exectest.cfg.
But when exectest READS from the open 'boot/boot.cfg', it gets zeroed
data. <<<<<<<<
I've tried a number of mkimage variations, like
grub-mkimage --format=i386-pc-pxe --output=pxegrub2
--prefix='(pxe)/boot' pxe pxecmd multiboot multiboot2
cat legacycfg test ls read
If it matters the grub legacy version works runs on Linux with qemu
(qemu-system-x86_64 -nographic -net nic,vlan=1 -net user,vlan=1 -tftp
/tmp/booto/ -boot n -bootp /pxegrub)
The grub (2) version is running on OSX with VirtualBox.
Any insights?
Thanks,
troy
