The EISA bus saw limited use between 1988 and 19 1995 when it was made obsolete by the PCI bus. 20 21 Say Y here if you are building a kernel for an EISA-based machine. 22 23 Otherwise, say N. 24 25config EISA_VLB_PRIMING 26 bool "Vesa Local Bus priming" 27 depends on X86 && EISA 28 default n 29 help 30 Activate this option if your system contains a Vesa Local 31 Bus (VLB) card that identify itself as an EISA card (such as 32 the Adaptec AHA-284x). 33 34 When in doubt, say N. 35 36config EISA_PCI_EISA 37 bool "Generic PCI/EISA bridge" 38 depends on !PARISC && PCI && EISA 39 default y 40 help 41 Activate this option if your system contains a PCI to EISA 42 bridge.

This database increases size of the kernel 69 image by about 40KB, but it gets freed after the system 70 boots up, so it doesn't take up kernel memory. Anyway, if 71 you are building an installation floppy or kernel for an 72 embedded system where kernel image size really matters, you 73 can disable this feature and you'll get device ID instead of 74 names. 75 76 When in doubt, say Y. 77
