Hi,
Does anyone have a 1542CF ("CF", not "A", "B", or "C") working in a
486 motherboard that uses the SiS chipset? Is it an ISA or EISA
motherboard?
I just got a cheap ISA/VLB motherboard that uses the SiS chipset,
and I cannot get FreeBSD (1.1 or 1.1.5.1) working with this combination.
Eventually, some process dies with an "illegal instruction" error (and
this fact gets printed to the console, which leads me to believe that it
is occurring in kernel code). Typically, gunzip dumps core at some
random point in the install process, during heavy disk I/O. ;-( I know
FreeBSD works, because I've got it running on another machine (also with
a 1542CF, but a different motherboard).
I've looked through the *BSD FAQ, the FreeBSD FAQ, and the systems
FAQ, and I can't find any mention of a system with *BOTH* a 1542CF and
the SiS chipset. I can find mentions of systems with one or the other,
but not both. [ As a side note, I do have a recent 1542CF -- one with
the SCSI signal rise/fall time hardware fix. ]
In tracking down this problem, I've swapped out just about every
part in the system, including the 1542CF, the 486 CPU, and the memory.
About the only things that haven't been swapped out are the motherboard,
power supply, and keyboard. I've also tried just about every
combination and permutation of motherboard setup configuration (e.g.,
ISA bus timing) and 1542CF timing configuration. I've also run the
1542CF diagnostics. Nothing seems to help.
Originally, I thought that this was a flaky motherboard, but I've
just started talking with someone who is also having problems with a
1542CF and a SiS motherboard. Now, I'm wondering if this isn't a
generic problem with the SiS chipset.
Does anyone have a 1542CF working with a SiS-based motherboard?
Thanks,
