I believe I posted this information in another thread a while back, but I will repeat it here for anyone else who happens to stumble on this one.
Although Microid Research does not seem to have released an MR-BIOS for the ALi M1419, they *did* release one for the FTDI 82C3480, so I assume if you could find a copy it would likely work on an M1419 board. VOGONS does have many of the MR-BIOS archived, but sadly not this one.
The same goes for the chipset documentation that was formerly on the AMI FTP server. M1419 is not listed, but "FTD" or "FTDI" is. This might be useful for anyone who wants to manipulate chipset registers on the M1419.

I think the confusion here is stemming from how Biostar relabels their chipsets. FTDI may very well have made an '82C3480', but if they did, it's likely quite unrelated to the actual chip that Biostar just so happened to relabel an '82C3480'.

Motherboard makers can be really obnoxious like this sometimes. (Micronics with their 'MIC 471' that's actually a relabeled SiS 461, anybody?)

Random pic of a Bioteq board in my stash. Don't recall running it in the past, and it's about 7 or 8 down the list of 486 stuff to play with. I might drag it out again to see if a 486SLC will go on that 386sx footprint, if one of the 486slc boards coming in turns out to be unfixable.

Nice board but looks like that Varta is fuzzy/leaking... better pull it while you have the board out before damage gets worse....

I’d have to check again, but I was pretty sure the AMIBIOS I was using on my board had “FTD” in the BIOS version string.

Looks like a relabeled UMC 82C491/493 chipset on that board to me. A pretty good chipset, but it will probably need dirty TAG SRAM to perform its best.
(You'll have to hack that in, on most boards with this chipset that omit the footprint for the dirty TAG SRAM.)

On my Biostar boards, it always said BIOTEQ in the version string - again, to be as obnoxious as possible. 🙃
