Interesting. However, I know some ROM are locked for some reasons. (Namely NVIDIA being 100% closed-source...)

Both are OTP, but why they are not supported (for read)?

I think some are OTP, others are flashable. You can check the datasheet to be sure.

Same here for Vanta (Atmel AT27LV512A).

Or it is intentionally to not support those 27's chips which are One-Time-Programmable?

Thanks for the info.

I've found that it MIGHT be supported by flashrom. It does look for memory (see log).

I checked the chip and it's Holtek ht27c512 (it's 64k - good sign?) which seems to be, simply, unsupported by flashrom.

Can You add its support?

Best regards!

32KB, I think. I do remember owning that card a long time ago. The BIOS image may be 16KB, however, due to very simple pipeline architecture. The only way to find out is to pull the BIOS copy and verify its size.
