NetBSD/x68k 1.2 runs on the Sharp X68030 series PCs with TRUE
MC68030 MPU (not MC68EC030) and FPU. Since the processor of
the X68030 series is MC68EC030RC25, you need to replace it
with MC68030RC25 (Simply remove the old chip and put the new one
instead. The largest difficulty might be to open your X68030).
In addition, some accelerators are supported:
Xellent030
Xellent030S
040turbo
Jupiter-X (040 / 060)
This means all models of X680x0 series PC except for CZ-600C
and CZ-674C, by using the appropriate accelerator, can run NetBSD!!
Note that the processor of Xellent030 series is MC68EC030, so
you need to replace your processor as well as for X68030.
The minimal configuration requires 4M of RAM and about 65M of
disk space. To install the entire system requires much more disk space,
and to run X or compile the system, more RAM is recommended.
Here is a table of recommended HD partition sizes for a full install:
partition: advise, with X, needed, with X
root (/) 15M 15M 10M 10M
user (/usr) 65M 100M 45M 80M
swap ----- 2M for every M ram -----
local (/local) up to you
As you may note the recommended size of /usr is 20M greater than
needed. This is to leave room for a kernel source and compile tree
as you will probably want to compile your own kernel. (ALL is
large and bulky to accommodate all people).
Supported devices include:
- Sharp genuine SCSI interface (builtin / optional)
* SCSI harddisks, CD-ROM drives, tape drives, scanners,...
- The builtin floppy drives
- The builtin frame buffer (both of the text and graphics screen)
- The builtin serial (RS-232C)
- The builtin parallel (Centronics printer interface)
- The standard keyboard
- The mouse / trackball
- NS16550 serial
- Neptune-X ethernet
Hopefully, the AD-PCM sound device and the Mankai SCSI interface
(Mach-2) will be supported on the next release.
