Hiding partitions, windows 2000 on second disk
When I type hide (hd0, and then press tab it lists 0 and 4 as possible partitions to hide. If I select 4, i.e. hide (hd0,4) it says Error this partion does not exist. ?? But anyway I worked around this by hiding the partitions using linux fdisk. The reason I was doing this was because I want to get windows 95 on (hd1,0). However if I map this drive to (hd0), or if I hide all the partitions on (hd0) so that dos makes (hd1,0) drive c:, when I run the windows SETUP program it starts by doing a scandisk, and then crashes on the second check (I forget what it is). Windows won't install without doing a scan disk. How am I going to get around this problem? ian ___ Bug-grub mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-grub
Booting a floppy image
Hey guys. I was wondering if it would be possible to boot a floppy image file with grub. (i.e. you could dd if=the_file.img of=/dev/fd0 and effectively boot off of it.) Is it possible to do this without needing the floppy? I ask because BeOS insists that I boot into the OS with this method, and it's sort of annoying. Thanks a lot :)) Adam ___ Bug-grub mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-grub
[PATCH]: Adds --ipappend to kernel command
While this is Linux specific, it's something we use here. I've patched
the stock grub 0.90 to add support for --ipappend on the kernel command
IF diskless support is enabled.
What does this do? It passes ip=ipnum:serverip:gateway:netmask to the
linux kernel from a dhcp request. We use it in systems here that the on
board ethernet card does not have the ability to do network boot. We use
grub on a floppy to boot the system simulate a network boot of Linux
on the system. grub takes the place of a boot ROM.
While we use it with our software in a special initrd to set the IP
number on the interface, it can be used to support nfsroot for Linux or
just plan autoconfiguration in the Linux kernel (check
linux/Documentation/nfsroot.txt). PXELINUX supports this option and we
use it to boot PXE enabled systems...so we just added it to grub to
netboot these boot ROMless servers.
The patch is included in the message below the sig.
It would be nice if the Grub maintainers would consider adding this
option to the mainstream grub code.
Thanks,

This is mentioned in the info sample menu section and nowhere else. It needs explanation. Nowhere can I find a file by this name nor any other reference to it. How does one use GRUB to boot OS/2 from (hd0,5)? Simply using uncommented portion of the example for OS/2 and substituting the 5 for the 1 does not work, and the commented portion with the subject file can't be used without that file. -- Our Constitution was made only for a moral and religious people.

Re: grub command works, but GRUB boot loader hangs
From earlier discussions in this thread we have concluded that
get_diskinfo_floppy() should go away. Attached below is a proposed
patch to remove it.
I've also reorganized the tail end of get_diskinfo() to unify the floppy
and non-floppy calls to get_diskinfo_standard(), which previously were
in distinct branches of a conditional. Someone should give that a
second look before checking it in to make sure that I haven't done
something boneheaded to the control flow.
