Can anyone post the modded bios somewhere else? Host has removed it.

You'd need to use a CPU of the same TDP (voltage and amperage) that has the same init process. Microcode updates are *NOT* necessary, just initialization aka init. Microcode is a bit like firmware in that the CPU can be given microcode to overlay its own during init or even at a later point, such as how Windows & Linux can use microcode for PCs without BIOS updates. As long as the CPU can be initialized, it *should* be possible. (I'm only adding this bit because I saw a few “we need microcode updates for that” posts, which is incorrect.) There are exceptions...and sometimes that occurs for laptops.
Also, for everyone curious: When unplugged, the laptop will run 8C16T (8 cores, 16 threads) at 600MHz. The BIOS is the one informing the system itself that it must do that when it is unplugged, presumably to protect the batteries from drawing too much current to stay alive. Linux and Windows will, by default, respect this and not interfere. It can be overridden...but I would not recommend drawing from these batteries like that. However...if the configuration could be changed, it'd make the laptop far more useful. Instead of all 8-cores 16-threads running at 600MHz, perhaps just disabling 6 cores (12 threads) to run as a 2-core 4-thread would draw the same current and be far faster? Say 2.4GHz per core instead? 8C16T@600MHz and 2C4T@2.4GHz would, by numbers, have the same processing power, maybe current draw might be close enough to current drawn with stock behavior to justify it. The single-thread performance would greatly reduce hitching and lag caused by 600MHz instead. No idea why ASUS didn't do this out of box... I don't mind the GPU downclocking and the CPU as well, but that's too little with way too many cores.
I made a custom battery pack out of 18650s for this laptop. The pain in the butt BMS was difficult to reliably weld the leads to, but I'm up to double battery life. Not that it matters much, considering it's crap to begin with xD. The 18650s I have also won't swell up like the stock battery. Best part is, the batteries themselves aren't welded/soldered in, they're replaceable, woo! ...Twice as long to charge, meh. Wish I had a 3D-printer though, ugly as all git of a setup.
If you're curious about the STOCK pinout of the BMS (serial only, each cell is ~4V, 4500mAh):
VP->BAT0+, positive rail for laptop
VM1->BAT1-
VH1->BAT0-
VH2->BAT1+
VM2->BAT3+
VG->BAT4-, negative rail for laptop
VL1->BAT3-
VL2->BAT4+
I merely went with 18650s and hooked up twice as many *IN PARALLEL* TO EACH CELL without disturbing the series after initially charging each "two-cell cell" with a BMS to get them nearly balanced well enough in charge to prevent issues when first charging. If you're not an electronics engineer or do not understand this, DO NOT ATTEMPT. You can blow things up accidentally.
Thinking about modding the bottom of my laptop to add in a battery 'bay' but I'd need a 3D-printer for that, meh. Custom bottom halfs and battery packs with DIY guide using stock BMS...people'd need a 3D-printer, a high-volt welder (for leads to BMS). Meh.
Also, many thanks to draklrd for his posted bin a while back, which allowed me to rescue my own laptop. I removed the win license and changed everything to match my own system details.
