Chameleon
The Chameleon bootloader is an APSL project based on David Elliott’s fake EFI implementation added to Apple’s boot-132 project.
The source code repository is available at http://forge.voodooprojects.org/p/chameleon/source/tree/HEAD/
Chameleon brings some nice features from low to high layers as: Preboot ramdisk image, EFI partition booting, hibernation/resume, DSDT and SMBIOS, GUI booting and custom themes supports.
draft.
Status
- Chameleon 2.0-RC4-r684 works with QEMU v0.10.6 and VMware (Fusion) 3.0.1 on a Mac.
- Chameleon 2.0-RC3-r658 works with QEMU (mac & win tested), VMware (Fusion), etc.. Prolematic points reached on windows with e.g. vmware (“Mach-o has bad magic number” error).
- Chameleon 2.0-RC1-r431 works with QEMU.
- Chameleon 2.0-RC1-r431 will not show up in VMware (observed in Fusion but not in Player), because VMware relies on darwin.iso (VMware Tools) which contains the DFE bootloader (Stage 2 boot file < 128K) is ok.
- In case of real hardware target, cdboot, boot, boot0 and boot1h have been deployed but not yet tested.
- In Image disk, virtual or not, cdboot and the “El Torito ISO trick” is used.
- Note: The error “Error parsing plist” in i386/libsaio/stringTable.c, the function “long ParseXMLFile( char * buffer, TagPtr * dict )” is responsible of returning the error.
if (length < 0) {
error ("Error parsing plist filen");
return -1;
}
Why is it failing? The plist is obviously well formated and there is no permission problem at this level. Problem: “Error parsing plist file” Solution: In fact, the error comes from the memory allocation, it seems that 256MB is not enough and make it fails in the contrary of e.g., 384M.
