And so I went and downloaded metoo 1.4.1... And indeed, enclosed were two versions of m8plus_16 (One with an eject fix, one without), both pre-patched with LBA48, IGR, and X2 style live blocking...
Also included is a hacked version of the latest (1.0.9) evtool that ignores bios hashes and can be used to modify those included BIOSes. (yay!)
After seeing this, I tried flashing the BIOSes to my Xenium ICE, and they did indeed work :-D.
I'll throw the source for PBL/metoo 1.4.1 online... NghtShd: could you add live blocking to evtool? (The relevent source files are m8plus_xbl_block_patch1.asm and m8plus_xbl_block_patch2.asm I'd think

)
Thanks!
