Silicon Image SIL3112 Flashing: Easier Way Using flashrom

[nikdoof]

A little more experimentation, I added a Apple branded SATA 2.5" HDD onto the SIL3112 card and booted with my known good OSX 10.4 from the SATA2IDE, the boot was extremely slow but it did get into OSX, and in System Information the HDD didn't show. Again, works perfectly fine and without issue in OS9. Removing the power from the HDD the system booted into OSX near instantly again.

It seems it's down to my Samsung Evo 750, Using the HDD for a OSX install works perfectly fine. Shame I didn't test this before investing in another card...

So I got a Kalea Informatique card off amazon, and found out it has the 12v fw chip, I have a AT29C010A chip I got for a different project (replacement of an Adaptec 2940 SCSI card) and I wanted to know if I could use it here for on-card flashing?

The 5V IC would get damaged at 12V. Often, these cards have SMD resistors that can be moved to set the voltage on the regulator down to 5V. I would look at the regulator's part number, and check the datasheet if it is adjustable. If so, try and find which resistor (or pads for a resistor) is/are responsible, and if it can be changed/placed/(re)moved to adjust it to 5V.

Yep, you can install that EEPROM no issue, then flash it on-board. That EEPROM runs at 5V, just like the original, so no need to change any resistor position. The only case in which that is necessary is if you switch to a 3.3V EEPROM, which are normally designated with an “LV” in their part number.

12V is only needed to erase and program the AM28F010 EEPROM, which is why it cannot be programmed on-board (the board has no way of supplying 12V needed). In normal operation, the EEPROM runs at 5V.

Haha, oops, serves me right for trying to multitask my work and 68kMLA
Never mind my last response!
