They12 were also used in servers from the E-class to the K-class. They13 are not found in B1000, C3000, J5000, A500, L1000, N4000 and upwards.14 If in doubt, say "Y".15 16config HPPB17 bool "HP-PB bus support"18 depends on GSC19 help20 The HP-PB bus was used in the Nova class and K-class servers.21 If in doubt, say "Y"22 23config IOMMU_CCIO24 bool "U2/Uturn I/O MMU"25 depends on GSC26 help27 Say Y here to enable DMA management routines for the first28 generation of PA-RISC cache-coherent machines. Programs the29 U2/Uturn chip in "Virtual Mode" and use the I/O MMU.30 31config GSC_LASI32 bool "Lasi I/O support"33 depends on GSC34 help35 Say Y here to support the Lasi multifunction chip found in36 many PA-RISC workstations & servers. It includes interfaces37 for a parallel port, serial port, NCR 53c710 SCSI, Apricot38 Ethernet, Harmony audio, PS/2 keyboard & mouse, ISDN, telephony39 and floppy. Note that you must still enable all the individual40 drivers for these chips.41 42config GSC_WAX43 bool "Wax I/O support"44 depends on GSC45 help46 Say Y here to support the Wax multifunction chip found in some47 older systems, including B/C/D/R class and 715/64, 715/80 and48 715/100. Wax includes an EISA adapter, a serial port (not always49 used), a HIL interface chip and is also known to be used as the50 GSC bridge for an X.25 GSC card.51 52config ISA53 bool "ISA support"54 depends on EISA55 help56 If you want to plug an ISA card into your EISA bus, say Y here.57 Most people should say N.58 59config GSC_DINO60 bool "GSCtoPCI/Dino PCI support"61 depends on PCI && GSC62 help63 Say Y here to support the Dino & Cujo GSC to PCI bridges found in64 machines from the B132 to the C360, the J2240 and the A180. Some65 GSC/HSC cards (eg gigabit & dual 100 Mbit Ethernet) have a Dino on66 the card, and you also need to say Y here if you have such a card.67 Note that Dino also supplies one of the serial ports on certain68 machines. If in doubt, say Y.69 70config PCI_LBA71 bool "LBA/Elroy PCI support"72 depends on PCI73 help74 Say Y here to support the Elroy PCI Lower Bus Adapter.
