the search for sata-os9 bootable firmware+card combination

[(S)ATAman]

holy crap, i really want to have one of those one day. why upgrade fom 2 to 4 when i can have 6?

the raid modes can hopefully be turned off.

all of them are PCI-X, not PCI-e.
The different cards are needed to check, how to turn the transparency off (if needed).
If the transparency is already off, that's a bonus.

In general, these cards present a pain in the butt because even if the transparency is off, I need to figure out how to address the ROM.
(Because we do not need the useless Adaptec firmware, we need OpenFirmware inside).

It's kind of a project for the next lock-down if COVID-20 or COVID-21 happens.

okay because it said PCIe https://www.ebay.com/itm/283528628048?ul_noapp=true

Yes, they made an obvious mistake. That card is I think made by LSI, not Adaptec.
The BOM is about the same, hopefully the internal design will be better.

Probably not the most important card in the collection of course - due the complicated and over-engineered bridge.
