The EISA bus saw limited use between 1988 and 18 1995 when it was made obsolete by the PCI bus. 19 20 Say Y here if you are building a kernel for an EISA-based machine. 21 22 Otherwise, say N. 23 24config EISA_VLB_PRIMING 25 bool "Vesa Local Bus priming" 26 depends on X86 && EISA 27 default n 28 ---help--- 29 Activate this option if your system contains a Vesa Local 30 Bus (VLB) card that identify itself as an EISA card (such as 31 the Adaptec AHA-284x). 32 33 When in doubt, say N. 34 35config EISA_PCI_EISA 36 bool "Generic PCI/EISA bridge" 37 depends on !PARISC && PCI && EISA 38 default y 39 ---help--- 40 Activate this option if your system contains a PCI to EISA 41 bridge. If your system have both PCI and EISA slots, you 42 certainly need this option. 43 44 When in doubt, say Y. 45 46# Using EISA_VIRTUAL_ROOT on something other than an Alpha or 47# an X86 may lead to crashes... 48 49config EISA_VIRTUAL_ROOT 50 bool "EISA virtual root device" 51 depends on EISA && (ALPHA || X86) 52 default y 53 ---help--- 54 Activate this option if your system only have EISA bus 55 (no PCI slots). The Alpha Jensen is an example of such 56 a system. 57 58 When in doubt, say Y. 59 60config EISA_NAMES 61 bool "EISA device name database" 62 depends on EISA 63 default y 64 ---help--- 65 By default, the kernel contains a database of all known EISA 66 device names to make the information in sysfs comprehensible 67 to the user. This database increases size of the kernel 68 image by about 40KB, but it gets freed after the system 69 boots up, so it doesn't take up kernel memory. Anyway, if 70 you are building an installation floppy or kernel for an 71 embedded system where kernel image size really matters, you 72 can disable this feature and you'll get device ID instead of 73 names. 74 75 When in doubt, say Y. 76
