The EISA bus saw limited use between 1988 and19 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_PRIMING26 bool "Vesa Local Bus priming"27 depends on X86 && EISA28 default n29 help30 Activate this option if your system contains a Vesa Local31 Bus (VLB) card that identify itself as an EISA card (such as32 the Adaptec AHA-284x).33 34 When in doubt, say N.35 36config EISA_PCI_EISA37 bool "Generic PCI/EISA bridge"38 depends on !PARISC && PCI && EISA39 default y40 help41 Activate this option if your system contains a PCI to EISA42 bridge. If your system have both PCI and EISA slots, you43 certainly need this option.44 45 When in doubt, say Y.46 47# Using EISA_VIRTUAL_ROOT on something other than an X86 may lead48# to crashes...49 50config EISA_VIRTUAL_ROOT51 bool "EISA virtual root device"52 depends on EISA && X8653 default y54 help55 Activate this option if your system only have EISA bus56 (no PCI slots).57 58 When in doubt, say Y.59 60config EISA_NAMES61 bool "EISA device name database"62 depends on EISA63 default y64 help65 By default, the kernel contains a database of all known EISA66 device names to make the information in sysfs comprehensible67 to the user. This database increases size of the kernel68 image by about 40KB, but it gets freed after the system69 boots up, so it doesn't take up kernel memory. Anyway, if70 you are building an installation floppy or kernel for an71 embedded system where kernel image size really matters, you72 can disable this feature and you'll get device ID instead of73 names.74 75 When in doubt, say Y.76
