New in 1.90 - 2005-08-07:
|
|
|
|
* Rename the project name PUPA to GRUB. Now this version is the
|
|
developmental version of GRUB officially.
|
|
|
|
* The GRUB emulator ``grub-emu'' is added.
|
|
|
|
* Add support for newworld Mac. This should work with other
|
|
PowerPC-based machines as well, if they use IEEE 1275
|
|
(Open Firmware).

|
|
New in 0.7:
|
|
|
|
* Problems in cross-compiling PUPA are fixed.
|
|
|
|
* Use -mrtd and -mregparm=3 to reduce the generated code sizes. This
|
|
means that any missing prototypes could be fatal. Also, you must take
|
|
care when writing assembly code. See the comments at the beginning of
|
|
startup.S, for more details.
|
|
|
|
* New utility, ``pupa-setup''. This sets up PUPA to make it bootable
|
|
from a real disk.
|
|
|
|
* New commands, "prefix", "insmod", "rmmod" and "lsmod" are added into
|
|
the rescue mode to manipulate PUPA modules.
|
|
|
|
* Linux support is added. Initrd is not support yet.
|
|
|
|
* Reduce the size of a core image significantly by compressing a large
|
|
part of the core image and decompressing itself at boot time. The
|
|
currently used algorithm is LZO (more precisely, LZO1X-999). So you
|
|
have to install LZO to build PUPA. See
|
|
<http://www.oberhumer.com/opensource/lzo/>, for more information.
