They 11 were also used in servers from the E-class to the K-class. They 12 are not found in B1000, C3000, J5000, A500, L1000, N4000 and upwards. 13 If in doubt, say "Y". 14 15config HPPB 16 bool "HP-PB bus support" 17 depends on GSC 18 help 19 The HP-PB bus was used in the Nova class and K-class servers. 20 If in doubt, say "Y" 21 22config IOMMU_CCIO 23 bool "U2/Uturn I/O MMU" 24 depends on GSC 25 help 26 Say Y here to enable DMA management routines for the first 27 generation of PA-RISC cache-coherent machines.

It includes interfaces 36 for a parallel port, serial port, NCR 53c710 SCSI, Apricot 37 Ethernet, Harmony audio, PS/2 keyboard & mouse, ISDN, telephony 38 and floppy. Note that you must still enable all the individual 39 drivers for these chips. 40 41config GSC_WAX 42 bool "Wax I/O support" 43 depends on GSC 44 help 45 Say Y here to support the Wax multifunction chip found in some 46 older systems, including B/C/D/R class and 715/64, 715/80 and 47 715/100. Wax includes an EISA adapter, a serial port (not always 48 used), a HIL interface chip and is also known to be used as the 49 GSC bridge for an X.25 GSC card. 50 51config ISA 52 bool "ISA support" 53 depends on EISA 54 help 55 If you want to plug an ISA card into your EISA bus, say Y here. 56 Most people should say N. 57 58config GSC_DINO 59 bool "GSCtoPCI/Dino PCI support" 60 depends on PCI && GSC 61 help 62 Say Y here to support the Dino & Cujo GSC to PCI bridges found in 63 machines from the B132 to the C360, the J2240 and the A180. Some 64 GSC/HSC cards (eg gigabit & dual 100 Mbit Ethernet) have a Dino on 65 the card, and you also need to say Y here if you have such a card. 66 Note that Dino also supplies one of the serial ports on certain 67 machines.
