I find it helps to break down the category of ‘consciousness.’ What is it that one is saying when one says that “Consciousness is essentially biological”? Here it’s important to be careful: there are philosophers who gerrymander categories. We can start by pointing to human beings, as we take human beings to be conscious, but obviously we aren’t pointing at every human attribute. (For instance, having 23 base pairs of chromosomes isn’t a characteristic we are pointing at.) We have to be careful that when we point at an attribute, that we are actually trying to solve the problem and not just obscure it: if I tell you that Consciousness is only explainable by Woogles, that’s just unhelpful. The term we use needs to break down into something that allows us to (at least in principle) tell whether or not a given thing is conscious. If it can’t do THAT, we are better off using our own biased heuristics and forgoing defintions: at least in the former case, I can tell you that my neighbor is conscious and a rock isn’t. Without some way of actually telling what is conscious and what is not, we have no basis to actually say when we’ve found a conscious thing.
It seems like with consciousness, we are primarily interested in something like “has the capacity to be aware of its own existence.” Now, this probably needs to be further explicated. “Awareness” here is probably a trouble word. What do I mean when I say that it is “aware”? Well, it seems like I mean some combination of being able to percieve a given phenomenon and being able to distinguish both degrees of the phenomenon when present and distinguishing the phenomenon from other phenomenon. When I say that my sight makes me aware of light, I mean that it allows me to both distinguish different sorts of light and light from non-light: I don’t mistake my sight for hearing, after all. So if I am “aware of my own existence” then I have the capacity to distinguish my existence from things that are not my existence, and the ability to think about degrees to which I exist. (in this case, my intuition says that this caches out in questions like “how much can I change and still be me?”)
Now, there isn’t anything about this that looks like it is biological. I suppose if we came at it another way and said that to be conscious is to “have neural activity” or something, it would be inherently biological since that’s a biological system. But while having neural activity may be necessary for consciousness in humans, it doesn’t quite feel like that’s what we are talking about when we talk about what we are pointing to when we say “conscious.” If somehow I met a human being and was shown a brain scan showing that there was no neural activity, but it was apparently aware of itself and was able to talk about how its changed over time and such and I was convinced I wasn’t being fooled, I would call that conscious. Similarly, if I was shown a human being with neural activity but which didn’t seem capable of distinguishing itself from other objects or able to consider how it might change, I would say that human being was not conscious.
You’ve chosen one of the easier aspects of cosnciousness: self-awareness rather than, eg. qualia.
The “necessarily biological” could be aposteriori nomic necessity, not apriori concpetual necessity, which is the only
kind you knock down in your comment.

I cover this a bit when I talk about awareness, but I find qualia to often be used in such a way as to obscure what consciousness is rather than explicate it. (If I tell you that consciousness requires qualia, but can’t tell you how to distinguish things which have qualia from things which do not, along with good reason to believe that this way of distinguishing is legitimate, then rocks could have qualia.)

If the defenders of a biological theory of consciousness want to introduce an empirically testable law to show that consciousness requires biology then I am more than happy to let them test it and get back to us. I don’t feel the need to knock it down, since when it comes to a posteriori nomic necessity, we use science to tell whether it is legitimate or not.
If we want to understand how consciousness works in humans, we have to accou t for qualia as part of it. Having an undertanding of human consc. is the best practical basis for deciding whether other entitieies have consc. OTOH, starting by trying to decide which entities have consc. is unlikely to lead anywhere.
The biological claim can be ruled out if it is incoherent, but not if it for being unproven, since the funciontal/computational alternative is also unproven.
Accounting for qualia and starting from qualia are two entirely different things. Saying “X must have qualia” is unhelpful if we cannot determine whether or not a given thing has qualia.
Qualia can perhaps best be described, briefly, as “subjective experience.” So what do we mean by ‘subjective’ and ‘experience’?
If by ‘subjective’ we mean ‘unique to the individual position’ and by ‘experience’ we mean ‘alters its internal state on the basis of some perception’ then qualia aren’t that mysterious: a video camera can be described as having qualia if that’s what we are talking about. Of course, many philosophers won’t be happy with that sort of breakdown. But it isn’t clear that they will be happy with any definition of qualia that allows for it to be distinguished.
If you want it to be something mysterious, then you aren’t even defining it. You are just being unhelpful: like if I tell you that you owe me X dollars, without giving you anyway of defining X. If you want to break it down into non-mysterious components or conditions, great. What are they? Let me know what you are talking about, and why it should be considered important.
At this point, it’s not a matter of ruling anything out as incoherent. It’s a matter of trying to figure out what sort of thing we are talking about when we talk about consciousness and seeing how far that label applies. There doesn’t appear to be anything inherently biological about what we are talking about when we are talking about consciousness. This could be a mistake, of course: but if so, you have to show it is a mistake and why.

We can tell that we have qualia, and our won consciousnessn is the ntarual starting point.
“Qualia” can be defined by giving examples: the way anchiovies taste, the way tomatos look, etc.
You are makiing heavy weather of the indefinability of some aspects of consciousness, but the flipside
of that is that we all experience out won consciousness. It is not a mystery to us. So we can substitute “inner ostension” for abstract definition.
