Re: /dev/tcx0 crashes SunOS 4.1.4 on Sparc 20's

-> If you try to read /dev/tcx0 on a SunOS 4.1.4 Sparc 20 (it didn't
-> work on a 10; didn't have access to a Sparc 5, so I couldn't check
-> that), you will cause a system panic.  How do you read it, you ask?
-> Simply "cat /dev/tcx0" or "ls /dev/tcx0/*".  You don't need special
-> privileges to use it.
->
-> Now, I have never own'ed a tcx frame buffer.  These only exist on Sparc 5
-> right?  So I don't know what will happen if you do have a tcx device.
-> If you don't, then the simplest fix is to just remove the darn entry under
-> /dev.

Hello,

this problem is descibe in Sun's Bug Id 1255965
Work around:
1. Install tcx frame buffer.
2. Edit GENERIC file as below and create new kernel.
< device-driver tcx             # 24-bit accelerated color frame buffer
---
> #device-driver        tcx             # 24-bit accelerated color frame buffer

bye
        Frank
