3.7 Setting the Test Options
The PROM on the
GXTRA
card contains a FORTH code driver.
The FORTH code is downloaded to the CPU during the power-up
sequence to give an on-board driver for the
GXTRA
card. If a
hardware problem is suspected, the user should run the diagnostic
routine called "gxtra-banner". The "gxtra-banner" performs a
"checksum" on the
GXTRA
firmware:
OK>
printenv fcode-debug?
If the environmental variable is set to "false", it must be set to "true"
by entering:
OK>
setenv fcode-debug? true
OK>
reset
Upon completion of the
reset
, the "gxtra-banner" will be available
for use. Access to this routine is dependent upon the version of the
Open Boot PROM that your system has. Generally if you are
running on a SPARCstation 2 or higher, you will have version 2.x
proms, and others will have version 1.x proms. To check the "ROM
Rev." of your system execute the following command:
