hardware revision 1.2
1 NetBSD/i386 1.0 runs on ISA (AT-Bus), EISA, PCI, and VL-bus systems 2 with 386-family processors, with or without math coprocessors. It 3 does NOT support MCA systems, such as some IBM PS/2 systems. The 4 minimal configuration requires 4M of RAM and 40M of disk space. To 5 install the entire system requires much more disk space, and to run X 6 or compile the system, more RAM is recommended. (4M of RAM will 7 actually allow you to run X and/or compile, but it won't be speedy. 8 Note that until you have around 16M of RAM, getting more RAM is more 9 important than getting a faster CPU.) 10 11 Supported devices include: 12 Floppy controllers. 13 MFM, ESDI, IDE, and RLL hard disk controllers. 14 SCSI host adapters: 15 Adaptec AHA-154xA, -B, -C, and -CF [only on kcaha floppy] 16 Adaptec AHA-174x 17 Adaptec AIC-6260- and AIC-6360-based boards, including 18 the Adaptec AHA-152x and the SoundBlaster SCSI 19 host adapter. (Note that you cannot boot from 20 these boards if they do not have a boot ROM, 21 and many do not.) 22 Buslogic 54x [AHA-154x clones; only on kcaha floppy] 23 Buslogic 445, 74x, 9xx [only on kcbt floppy] 24 NCR 53C810 PCI SCSI host adapter 25 Ultrastor 14f, 34f, and (possibly) 24f 26 MDA, CGA, VGA, SVGA, and HGC Display Adapters. (Note that not 27 all of the display adapters NetBSD/i386 can work with 28 are supported by X. See the XFree86 FAQ for more 29 information.) 30 Serial ports: 31 8250/16450-based ports 32 16550-based ports 33 AST-style 4-port serial boards [*] 34 IBM PC-RT 4-port serial boards [*] 35 Parallel ports. 36 Ethernet controllers: 37 AT&T StarLAN 10, EN100, and StarLAN Fiber 38 3COM 3c501 [*] 39 3COM 3c503 40 3COM 3c505 [*] 41 3COM 3c507 42 3COM 3c509 and 3c579 43 Digital DEPCA [*] 44 BICC Isolan [* and not recently tested] 45 SMC/WD 8003, 8013, and the SMC "Elite16" ISA boards 46 SMC/WD 8216 (the SMC "Elite16 Ultra" ISA boards) 47 Novell NE1000, NE2000 48 Novell NE2100 [* and not recently tested] 49 Tape drives: 50 Most SCSI tape drives 51 QIC-02 and QIC-36 format (Archive- and Wangtek- 52 compatible) tape drives [*] 53 CD-ROM drives: 54 Mitsumi CD-ROM drives [*] 55 Most SCSI CD-ROM drives 56 Mice: 57 "Logitech"-style bus mice [*] 58 "Microsoft"-style bus mice [*] 59 "PS/2"-style mice [*] 60 Serial mice (no kernel support necessary) 61 Miscellaneous: 62 SoundBlaster [*] 63 64 Drivers for hardware marked with "[*]" are NOT included on the 65 distribution floppies. Except as noted above, all other drivers are 66 present on both kernel-copy disks. Also, at the present time, the 67 distributed kernels support only one SCSI host adapter per machine. 68 NetBSD normally allows more, though, so if you have more than one, you 69 can use all of them by compiling a custom kernel once NetBSD is 70 installed. 71 72 Hardware the we do NOT currently support, but get many questions 73 about: 74 Adaptec AIC-7770-based SCSI host adapters (including the 75 Adaptec AHA-274x, AHA-284x, and AHA-294x families). 76 Intel EtherExpress Ethernet boards. 77 NCR 5380-based SCSI host adapters. 78 PCMCIA devices. 79 QIC-40 and QIC-80 tape drives. (Those are the tape drives 80 that connect to the floppy disk controller.) 81 WD-7000 SCSI host adapters. 82 83 We are planning future support for most of these devices. 84 85 To be detected by the distributed kernels, the devices must 86 be configured as follows: 87 88 Device Name Port IRQ DRQ Misc 89 ------ ---- ---- --- --- ---- 90 Serial ports com0 0x3f8 4 [8250/16450/16550/clones] 91 com1 0x2f8 3 [8250/16450/16550/clones] 92 com2 0x3e8 5 [8250/16450/16550/clones] 93 94 Parallel ports lpt0 0x378 7 [interrupt-driven or polling] 95 lpt1 0x278 [polling only] 96 lpt2 0x3bc [polling only] 97 98 MFM/ESDI/IDE/RLL hard disk controller 99 wdc0 0x1f0 14 [supports two disks] 100 101 Floppy controller 102 fdc0 0x3f0 6 2 [supports two disks] 103 104 AHA-154x, AHA-174x (in compatibility mode), or BT-54x SCSI host adapters 105 aha0 0x330 any any [only on kcaha kernel floppy] 106 107 AHA-174x SCSI host adapters (in enhanced mode) 108 ahb0 any any any 109 110 BT445, BT74x, or BT9xx SCSI host adapters 111 bt0 0x330 any any [only on kcbt kernel floppy] 112 113 Ultrastor 14f, 24f (if it works), or 34f SCSI host adapters 114 uha0 0x330 any any 115 116 AHA-152x, AIC-6260- or AIC-6360-based SCSI host adapters 117 aic0 0x340 11 6 118 119 NCR 53C810 PCI SCSI host adapter 120 ncr0 any any any 121 122 SCSI disks sd0 first SCSI disk (by SCSI id) 123 sd1 second SCSI disk (by SCSI id) 124 sd2 third SCSI disk (by SCSI id) 125 sd3 fourth SCSI disk (by SCSI id) 126 127 SCSI tapes st0 first SCSI tape (by SCSI id) 128 st1 second SCSI tape (by SCSI id) 129 130 SCSI CD-ROMs cd0 first SCSI CD-ROM (by SCSI id) 131 cd1 second SCSI CD-ROM (by SCSI id) 132 133 SMC/WD 8003, 8013, Elite16, and Elite16 Ultra Ethernet boards, 3c503, 134 Novell NE1000, or NE2000 Ethernet boards 135 ed0 0x280 2 iomem 0xd0000 136 ed1 0x250 2 iomem 0xd8000 137 ed2 0x300 10 iomem 0xcc000 138 139 3COM 3c509 or 3COM 3c579 Ethernet boards 140 ep0 any any 141 142 AT&T StarLAN 10, EN100, or StarLAN Fiber, or 3COM 3c507 Ethernet boards 143 ie0 0x360 7 iomem 0xd0000 144
