Hi,
I replaced the NVRAM's in 2 recently acquired IPX's, they were real
M48T02 chips and not the Dallas Semi known to have problems in IPX's.
The POST claims it read 7f out of the register at f20007fa rather than
ff.
The NVRAM FAQ claims 7f is what it SHOULD read since this is the
minutes register and the high bit should be 0.
Ideas? Thoughts? Does NetBSD handle the "Kickstart" process automatically
like Solaris does? I ran the process manually but it didn't change the
POST results.
Can I override the POST test with the nvrc? The failed POST prevents
autobooting from working. B^(.
NVRAM seems to keep time and eeprom parameters OK.
Is the POST test just plain broken for more modern NVRAM chips?
Any info, pointers or fixes appreciated.
