Hello all,
Just want to find the model number of an MFM controller board please.
Attached ahead the eeprom dump, if it can be useful to someone one day 😀
Many thanks!

No clue and have never seen a Cirrus Logic chip on any MFM controller yet.

Nie tylko, jak widzicie, w tym trudność, że nie zdołacie wejść na moją górę, lecz i w tym, że ja do was cały zejść nie mogę, gdyż schodząc, gubię po drodze to, co miałem donieść.
See also this card...
FHG5UA-IOS - 1986-10-06 - Taiwan Mycomp Corporation - Taiwan
FHH5UA-DGP - 1987-12-08 - Tiva Microcomputer Corporation (TMC) - United States
Looks like different divisions of the same company...

And the model name seems to be DC2-1.00
aligns perfectly with their naming convention, see eg. PUMA200-1.40 , IFSP-1.00 , IFSP-1.20

Sure it's MFM? Never seen a standard AT MFM controller with a boot ROM. Looks more like ESDI than MFM to me.

That ROM looks like firmware running on the onboard microcontroller, rather than BIOS extension running on the CPU.

Good eye ! Yes that is a TMC logo. Unfortunately their website archive does not list any hard drive adapters, except a pci scsi:

Cirrus logic SHD260 were also used on IDE hard drives. Slow controller chipset.

TMC provided a driver for 3rd and 4th floppy drives connected to that controller...

Agree ! Based on this: https://retrocmp.de/hardware/tmc-ifsp/tmc-ifsp.htm which uses same floppy controller DP8473v, DC2.sys should work.
