I think it's the last found, didn't find any newer one (it's from an archive called s68bios.zip).
That is the one I have. Ok. I am going to have to do this the hard way.... The board is throwing Memory Parity errors for me when I try to boot to DOS and even sometime with going to the BIOS. This only happens when I put in 192MB of RAM and more frequently when I go all the way up to 256MB of RAM. At 64MB and 128MB the system seems solid. So basically when you have 12 or 16 sticks of RAM in there is when problems show up. Strangely I have ran MEM-TEST for over a day with 192M in and got one error in 5 passes and then again with the same 12 sticks with an additional four (total 256MB) with no error. Swapping memory around has not helped (I have a total of 20 sticks). I tried testing the memory in my SIM-CHECK II but it does not like the sticks. I am trying to get the firmware updated and see if that helps so I can test individual sticks. In the mean time I am thinking the following:
1. Bad Sticks (unlikely)
2. Bad memory slots (I hope not)
3. Bad motherboard (I really hope not and seems unlikely)
Of course 1 is the only thing I can fix. With 2 I could always limit myself to 128MB of RAM which is more then enough of course but not as cool! At 3 I am screwed but I have hope given the fact that board seems stable with only 8 sticks in use.
There is a fourth choice: power. The MB is using a 430W PSU (I forgot the brand but it actually was a decent one). However, this mobo uses THREE power connectors. It will work with two but I am wondering when you start loading it up with memory and a high powered VLB card if it isn't having little fluctuations causing parity errors. The third power is three ground and three 5V rails. I am wondering if I could use a second PSU to supply power on the third connector and see if it make a difference or take power from a FDD/HDD power output on the same PSU. Thoughts anyone?
