Dear flashrom folks,
We still have some very old systems, where we need to update the firmware so that it can start GRUB from the MBR. The systems seem to consists out of two boards with a separate chipset and flash ROM chip. Reading the 1 MB SST49LF080A seems to work. I haven’t tried writing yet. ``` $ sudo ./flashrom -p internal -r tyan-vx50-b4985.rom flashrom p1.0-148-ge2cbb12 on Linux 4.14.87.mx64.236 (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found chipset "NVIDIA CK804". Enabling flash write... OK. Warning: unexpected second chipset match: "NVIDIA CK804" ignoring, please report lspci and board URL to flashrom@flashrom.org with 'CHIPSET: your board name' in the subject line. Found SST flash chip "SST49LF080A" (1024 kB, LPC) mapped at physical address 0x00000000fff00000. Reading flash... done. $ lspci -nn 00:00.0 Memory controller [0580]: NVIDIA Corporation CK804 Memory Controller [10de:005e] (rev a4) 00:01.0 ISA bridge [0601]: NVIDIA Corporation CK804 ISA Bridge [10de:0051] (rev f1) 00:01.1 SMBus [0c05]: NVIDIA Corporation CK804 SMBus [10de:0052] (rev a2) 00:02.0 USB controller [0c03]: NVIDIA Corporation CK804 USB Controller [10de:005a] (rev a2) 00:02.1 USB controller [0c03]: NVIDIA Corporation CK804 USB Controller [10de:005b] (rev a4) 00:06.0 IDE interface [0101]: NVIDIA Corporation CK804 IDE [10de:0053] (rev f3) 00:07.0 IDE interface [0101]: NVIDIA Corporation CK804 Serial ATA Controller [10de:0054] (rev f3) 00:08.0 IDE interface [0101]: NVIDIA Corporation CK804 Serial ATA Controller [10de:0055] (rev f3) 00:09.0 PCI bridge [0604]: NVIDIA Corporation CK804 PCI Bridge [10de:005c] (rev f2) 00:0a.0 Bridge [0680]: NVIDIA Corporation CK804 Ethernet Controller [10de:0057] (rev f3) 00:0b.0 PCI bridge [0604]: NVIDIA Corporation CK804 PCIE Bridge [10de:005d] (rev f3) 00:0c.0 PCI bridge [0604]: NVIDIA Corporation CK804 PCIE Bridge [10de:005d] (rev f3) 00:0d.0 PCI bridge [0604]: NVIDIA Corporation CK804 PCIE Bridge [10de:005d] (rev f3) 00:0e.0 PCI bridge [0604]: NVIDIA Corporation CK804 PCIE Bridge [10de:005d] (rev a3) 00:18.0 Host bridge [0600]: Advanced Micro Devices, Inc.

Does flashrom have the infrastructure to read (and write) the second chip? Kind regards, Paul [1]: https://paste.flashrom.org/view.php?id=3226
