I've an emachines®/acer® EL1210-09 (Advance Micro Devices Inc. Athlon LE-1620 (P/N ADH1620IAA5DH); nVIDIA® nForce® 780a SLI with planar C77 a2 GPU; nVIDIA® GF119 a1 GPU on PCIe 2.0 x16 slot). The system DMesg predictably detects no EISA resources on probing platform eisa.0, so EISA.c and related headers can be compiled as a module with no effect on my system's kernel initialization. AFAIK, Intel PCI has replaced EISA on all x86 and x86_64 systems built after 2000. The following redact from /var/log/dmesg.0 on 17 July 2021 illustrates typical info:
