NetBSD/i386 _VER runs on ISA (AT-Bus), EISA, PCI, and VL-bus systems with 386-family processors, with or without math coprocessors. It does NOT support MCA systems, such as some IBM PS/2 systems. The minimal configuration is said to require 4M of RAM and 50M of disk space, though we do not know of anyone running with a system quite this minimal today. To install the entire system requires much more disk space (the unpacked binary distribution, without sources, requires at least 65M without counting space needed for swap space, etc), and to run X or compile the system, more RAM is recommended. (4M of RAM will actually allow you to run X and/or compile, but it won't be speedy. Note that until you have around 16M of RAM, getting more RAM is more important than getting a faster CPU.) Supported devices include: Floppy controllers. MFM, ESDI, IDE, and RLL hard disk controllers. SCSI host adapters: Adaptec AHA-154xA, -B, -C, and -CF Adaptec AHA-174x Adaptec AIC-6260 and AIC-6360 based boards, including the Adaptec AHA-152x and the SoundBlaster SCSI host adapter. (Note that you cannot boot from these boards if they do not have a boot ROM; only the AHA-152x and motherboards using this chip are likely to be bootable, consequently.) Adaptec AHA-2x4x[U][W] cards and some onboard PCI designs using the AIC78X0 chip. There is a known problem using this driver with AHA-2742 cards or AIC7770 or AIC78[56]0 based embedded designs and multiple targets, due to resource contention which is not handled well by NetBSD's higher-level SCSI subsystem.

Except as noted above, all drivers are present on all disks. Also, at the present time, the distributed kernels support only one SCSI host adapter per machine. NetBSD normally allows more, though, so if you have more than one, you can use all of them by compiling a custom kernel once NetBSD is installed. Support for devices marked with "[+]" IS included in the "generic" kernels, although it is not in the kernels which are on the distribution floppies. Support for devices marked with "[b]" requires BIOS support for PCI-PCI bridging on your motherboard. Most reasonably modern Pentium motherboards have this support, or can acquire it via a BIOS upgrade. Hardware the we do NOT currently support, but get many questions about: AMD PCscsi SCSI host adapters (though the PCnet portion of the PCnet-SCSI works fine) Intel EtherExpress 100 Fast Ethernet adapters. Multiprocessor Pentium and Pentium Pro systems. (Though they should run fine using one processor only.) NCR 5380-based SCSI host adapters. PCI WD-7000 SCSI host adapters. PCMCIA ("PC Card") devices, including some miniature "IDE" hard disks. [Note: some higly experimental PCMCIA support is available on our FTP sites] QIC-40 and QIC-80 tape drives. (Those are the tape drives that connect to the floppy disk controller.) We are planning future support for many of these devices.
