After typing
showrev
at the command line, information similar to the following will be displayed on your
screen:
*************** showrev version 1.15 *****************
* Hostname: ”your machine name”

The last line indicates that this machine is running Revision A of SunOS 4.1.3_U1. If the machine were
running Revision B of SunOS 4.1.3_U1, the line would read:

A.5 SunOS 4.1.4 Issues
The SunOS 4.1.4 (Solaris 1.1.2) operating system is not directly bootable by hyperSPARC modules of speeds
55, 66 and 72 MHz. All hyperSPARCs of speeds 90MHz and higher will run 4.1.4 without modification. This
problem pertains
only to hyperSPARC processors of speeds 72MHz and slower. If you attempt to boot the
SunOS 4.1.4 CD on 72MHz or slower hyperSPARC it will fail with the message
“Level 15 Interrupt”
.
Problem Solutions
SunOS 4.1.4 incorporates the available patches of SunOS 4.1.3_U1 and some bug fixes. If your are installing
SunOS 4.1.4 there are ways to accomplish this with hyperSPARC. First, you can use either a 90MHz or faster
hyperSPARC processor or any SuperSPARC to boot and install SunOS 4.1.4 on a system. Once installed
you must make a modification to the kernel (
/vmunix
) to support the slower-than-90MHz hyperSPARCs.
This can either be done by hand with
adb
or with the shell script
414fix
found on the ROSS anonymous
ftp site in the directory
/pub/hypersparc–docs.
To modify it by hand invoke
adb
as root:
# adb –w /vmunix
(
adb
has no prompt. Type in the next line)
ross625_vac_i0x58?XXX
(
adb
should print the next line. If not, something is wrong!)
_ross625_vac_i0x58: c0a00620 81c3e008 1000000
(Type the following line)
ross625_vac_i0x58?W 1000000 81c3e008 c0a00620
(
adb
will print the following three lines)
_ross625_vac_i0x58: 0xc0a00620 = 0x1000000
_ross625_vac_i0x5c: 0x81c3e008 = 0x81c3e008
_ross625_vac_i0x60: 0x1000000 = 0xc0a00620
(Exit
adb
by typing the next line)
