Hello everyone,
I have just discovered flashrom, and was intrigued to find that it's possible to write PLCC chips by using an old PCI ethernet card. I have thus acquired for real cheap an SMC1211 card which is correctly identified by my Debian install:
00:0b.0 0200: 1113:1211 (rev 10)
I have an old BIOS chip, a PMC Pm49FL004T-33JCE that I would like to work on, but flashrom does not seem to recognise the chip, and a verbose dump did not help either, here is the dump:

Now, the Pm49FL004 is a 512k chip, and I see that flashrom probes for many different types of 512k chips, so this means that the nicrealtek program should be able to address the 512k chips. So why does the PMC list of chips probed does not include the Pm49FL004, but only shows these chips:

I check the flashchips.c file and thus I presume the issue lies in the fact that Pm49FL004 only supports LPC and FWH and not the BUS_PARALLEL access, so I am out of luck with the nicrealtek.c strategy.
Can anything be done at the nicrealtek.c level to support LPC, or is it a hardware limitation of the ethernet NIC?
What other hardware could I use in order to read and write the Pm49FL004 chip, other than a stand-alone programmer?
Thanks for any support given!
Best regards,
