Mine just pop up a prompt on boot (well, one prompt for the two cards, and I can switch between them in the BIOS). Maybe boot settings are hiding that somehow? Or maybe your model just doesn’t do it. Afraid I have no idea either way 
I have a couple reverse, and a few forward breakout cables. No noticeable difference on the cables or connectors (apart from labels I applied to the reverse ones)
I tried disabling quiet boot, but all it says is “press delete to enter bios”. But that bios is the motherboard bios, not the LSI bios.
Can you get the megasas or MegaCLI program to run? not sure if it works on powershell, but there should be an app with the driver file for from the Broadcom/avaya/LSI webpage?
Might get more info from that?
Ok so saga update. By changing the motherboard settings to “legacy” mode for boot roms I was able to get it to load the LSI rom. However, booting into that I didn’t see anything that would really help? I’m still waiting on the new cables, but at this point I am beginning to think something is just mis-configured, but I am too much of a noob to figure it out.
Perhaps the great @wendell will grace me with his knowledge of HBAs and what I need to do so this thing works with my windows 10 machine?
My LSI (a little different model) shows exactly how many drives are connected (Physical Disk Count).
And those reverse/non-reverse cables caused very similar issue for me in the past. Some stores descriptions does not help in that matter at all.

That image doesn’t appear to load.
Can anybody tell me why the sas2flash is throwing this error?

During boot there is a message like press ctrl a to enter megaraid bios
Do you see that ?
Got pics of your card?
Thx

@wendell When I changed to legacy mode I can get it so that I see the “press ctrl-c to enter bios” Give me a minute and I will send a picture of the card (got to remove it first)
ok, good. go to sas topology and see if you see the drives in that menu anywhere?
looking good. btw that card will get super hot and needs a lottttt of airflow over it to keep it cool
Yup, my fingers got a little burn moving it out to get a picture. I will check the topology and be back
For reference, here are the cables I originally ordered https://www.amazon.com/gp/product/B07CKX62L6
And just to rule out it being the cables I ordered these https://www.amazon.com/gp/product/B004KDO22K which should be here tomorrow
can you take some pics of your cabling setup? cable is pushed all the way into the card till it clicks?
https://photos.app.goo.gl/MyPTryoQ37fuXss86 ignore the fact it isn’t hooked up. The drive just keeps spinning so I disconnected it. Pardon the terrible lighting, my office doesn’t have overhead light so I had to use a flashlight.
I removed the cables and re-seated them multiple times to make sure they were connected (even heard a satisfying click).
The case is a fractal design r5 (cause I need a media drive bay on the front and all new cases seem to just be pure mesh). The cables are routed in through the rubber grommet area to the back and plugged in.
ok so lets do this. plug in all the power to all the drives, then plug one drive in with a sata cable to the motherboard to be sure the motherboard can see it.
shut down the computer
then without unplugging power to the hard drives, unplug the sata cable and plug in the sas cable and go back into ctrl+a and see if the drive can be seen?
I previously had 5 of the drives directly attached to the motherboard (limit of 6 sata ports on the motherboard, 1 of them being used for optical media) and they were working fine. Does it matter if the drives previously had something on them?
