@ -84,8 +84,12 @@ If you have a non-linux based switch (eg ICX6610) and you REALLY want to extract
Now run the following in the bootloader:
```
#dump the first 32MB of flash (this is usully enough)
dd f4000000 8388608
#alternatively, dump the full 64MB flash chip
dd f4000000 16777216
```
It will start printing the raw flash contents line by line in your serial window for a second, then stop. When it stops, press enter (NOT space), to make it continue dumping without user input, so it will dump overnight, and putty will be logging it.
This will take about 10 hours, so go to bed. In the morning, reboot the switch, and take a look at your putty log file. The dump will only be in raw hex, not ASCII - so to find your license strings you need to search the dump for `2a4220` which is the license start string `*B ` in hex. Once you find that, copy the following several blocks of hex values and paste them all into an online hex to ASCII converter, and you should get your string. Make sure you don't paste the leading memory address bits like `f40001e0:` into the converter.

Press tab twice and it'll show you all possible commands (just typing `help` will not show you all commands), there's a couple hundred, most of the utilities you'd expect including `wget`, `curl`, `vi`, and `ftpput`.

## Extra: Disable ThirdPartyPCIFanResponse

The LSI firmware is not supported by Dell. This will cause the iDRAC to no longer keep track of the drive temperatures. This is confirmed with the error PCI3018 in the Lifecycle Log and the fans being set to a static speed of about 30%. The fan speed acts as a failsafe to prevent any disks from possibly overheating.
iDRAC does not expect to see a PERC card running LSI firmware - this will cause the iDRAC to no longer see the drive temperatures. In some cases, this will cause the error PCI3018 in the Lifecycle Log, and the fans will be set to a static speed of about 30%. The fan speed acts as a failsafe to prevent any disks from possibly overheating.
To correct this behavior, you can disable the "ThirdPartyPCIFanResponse" feature by using IPMItool or RACADM. IPMItool is built into the live image so this will usually be the easiest option. If you are no longer booted into the live image, use the RACADM option instead to disable via SSH.
If you are affected by this and would like the fan behavior to return to normal, you can disable the `ThirdPartyPCIFanResponse` feature by using IPMItool or RACADM. IPMItool is built into the live image so this will usually be the easiest option. If you don't want to use the Linux live ISO, you can use the RACADM option to disable it via SSH.

## Extra: Revision Info & Part Numbers
The main difference between the B0 and D1 revisions is the D1 will link at PCIe 3.0 speeds, instead of PCIe 2.0. This will almost certainly never cause a bottleneck unless you have every SAS port on the card connected to very fast SSDs that all get hammered at the same time. Even then, you're likely to reach the card's processor limitations before the bus bandwidth limit. The difference with the *P* cards (H710P) is more cache (1GB vs 512MB), but this is totally irrelevant when running the card flashed to IT mode as the cache is not used.
