First post, by alfer
So I finally had it with procrastination and having all the hardware on hand decided to build my 3-year overdue DX66 machine.
My current pick is Shuttle Hot-419. It is Opti-based and has a welded coin cell rechargeable battery (not from factory, though some revisions do have an actual battery holder). Nice one overall, but I would really like to start it off with SiS. SiS with Amibios WinBios 2+VLB and CR2032, to be exact.
The problem is I'm unable to find (the facts of existence of) anything decent other than ever so popular AOpen VI15G.
And on the topic of indecent there are only 2 other candidates, according to elhvb:
I would probably bite the bullet and buy VI15G if it's the only real option out there. A few nays - want it to be dated =<94 (likely not the case here), annoyed by the soldered molex connector, don't like Acer all that much.
Reassuring suggestions are appreciated! Hard truths as well.
With the help of Deksor's wonderful Ultimate Hardware DB 2019, elhvb, an obscure japanese webpage http://home.att.ne.jp/alpha/pcboard/486.htm and google I was able to greatly expand the list. Keep in mind that it's not by any means complete, as even somewhat documented boards often do not show the battery in it's diagram and don't have a single searchable photo. I would expect that some of the Phoenix mainboards could come with AMI Bios as well (and vise versa) and have different kind of RTC battery, depending on revision.
