The EISA bus saw limited use between 1988 and 1962306a36Sopenharmony_ci 1995 when it was made obsolete by the PCI bus. 2062306a36Sopenharmony_ci 2162306a36Sopenharmony_ci Say Y here if you are building a kernel for an EISA-based machine. 2262306a36Sopenharmony_ci 2362306a36Sopenharmony_ci Otherwise, say N. 2462306a36Sopenharmony_ci 2562306a36Sopenharmony_ciconfig EISA_VLB_PRIMING 2662306a36Sopenharmony_ci bool "Vesa Local Bus priming" 2762306a36Sopenharmony_ci depends on X86 && EISA 2862306a36Sopenharmony_ci default n 2962306a36Sopenharmony_ci help 3062306a36Sopenharmony_ci Activate this option if your system contains a Vesa Local 3162306a36Sopenharmony_ci Bus (VLB) card that identify itself as an EISA card (such as 3262306a36Sopenharmony_ci the Adaptec AHA-284x). 3362306a36Sopenharmony_ci 3462306a36Sopenharmony_ci When in doubt, say N. 3562306a36Sopenharmony_ci 3662306a36Sopenharmony_ciconfig EISA_PCI_EISA 3762306a36Sopenharmony_ci bool "Generic PCI/EISA bridge" 3862306a36Sopenharmony_ci depends on !PARISC && PCI && EISA 3962306a36Sopenharmony_ci default y 4062306a36Sopenharmony_ci help 4162306a36Sopenharmony_ci Activate this option if your system contains a PCI to EISA 4262306a36Sopenharmony_ci bridge.

This database increases size of the kernel 6962306a36Sopenharmony_ci image by about 40KB, but it gets freed after the system 7062306a36Sopenharmony_ci boots up, so it doesn't take up kernel memory.
