4 \*V runs on several of the older Macintosh computers.
5 About 4 MB of RAM is sufficient to boot a stripped-down custom kernel, and a
6 subset of the system can be squeezed onto a 40 MB hard disk with considerable
7 creativity and persistence. However, 100 MB of disk should be considered a
8 practical minimum, and to do anything more interesting than booting at least
9 8 MB of RAM and more disk space is recommended.
11 Please note that to install
15 method, your system must have a minimum of 6 MB of RAM and 60 MB of
16 available disk space (i.e. not part of an in-use HFS partition).

46 .(bullet -compact -offset indent
47 Onboard SCSI bus and most SCSI tapes, hard drives, and CD-ROMs
49 Internal sound \(em enough to beep on some machines, anyway
51 Most basic NuBus video cards (there have been some
52 problems with some 24-bit color cards and with most
53 QuickDraw accelerators)
55 Both internal serial ports
57 ADB keyboards and mice (both Apple and a number of third party
58 multi-button mice and trackballs are supported)
60 Ethernet cards based on the National Semiconductor 8390 and the
62 (Asante, Apple, and a few others \(em problems still
63 with Ethernet and many NuBus video cards)
65 Ethernet cards based on the SMC 91c92 and 91c100 (FEAST) chips.
66 This includes the AsanteFAST 10/100 cards
68 Onboard Ethernet based on the SONIC chip for Quadra-series Macs
70 Onboard Ethernet based on the MACE (Am79C940) chip for the Quadra
73 Ethernet port on Asante NetDock and Newer Ether MicroDock,
74 for PowerBook Duo series
76 Comm-slot Ethernet should be working for most machines/cards
79 If your 68030 system is not listed above, it may be because of a problem
80 with accessing onboard video, and it may still work with a serial console.

88 If your 68LC040 system is not listed above, it is due to a problem with
89 floating point emulation (FPE) for this type of processor. Machines in

103 This machine has unusual custom chips for the ADB and serial interfaces
104 which make support for it difficult. Work is in progress on this, though.
108 These machines have I/O processor chips for their ADB interfaces similar to
109 those used in the IIfx and thus face similar support problems. Note that you
110 can use a serial console on these systems.
114 This is a separate effort from the \*M port. PowerMacs use hardware that
115 is quite different from that of the \*M port. See the
118 .Lk http://www.NetBSD.org/ports/macppc/
119 for more information.
122 .Ss2 Known hardware issues with this release
123 .(bullet -offset indent
126 Due to oddities of the Macintosh hardware interrupt priority scheme,
128 keeps very poor time. Under a high interrupt load (e.g.
129 SCSI or serial port activity), a machine can lose several minutes
130 per hour. A consequence of this problem is that attempting to run
132 is generally rather pointless.
138 SCSI drivers are not quite as
141 counterparts. Symptoms of these
142 problems are that some SCSI disks will not work under
143 NetBSD that work fine under
145 Other problems include
146 occasional file system corruption with some types of drives
147 and the general unreliability of removable SCSI media.
148 Keep in mind that there are no clear patterns with these
149 problems, and they do not appear to affect the majority of
