Extending WiFi : DD-WRT Repeater Bridge

Base              TP-Link TL-WDR3600 v1 (link to firmware)

Extender       Cisco Linksys E4200 (link to firmware)

DD WRT version  DD-WRT v3.0-r44340 std (09/10/20)

I had an earlier version working for a while and when I changed passphrase, it all fell apart. So I redid it. 

The main trouble on following the wiki instructions was that wireless and wired clients would connect to the extender, but not get an IP address. Client Brige config worked fine. So back to the repeater bridge. I added an AP to the extender on the second wifi band and it works fine now. I realize this is not recommended by the wiki. 

So use at your own caution. I'd still suggest following the wiki instructions above. If all else fails, try adding an AP .

Adding NVME boot support to Asrock Z68 Pro3

 This is possible and it worked for me. However, use at your own risk: Flashing BIOS is risky.

  The main idea is from this post.

Notes:

1. Original BIOS version was 2.30  . This had padded sections so I couldn't use UEFITool. MMtool worked fine to insert NVME support. 
2. Older BIOSes had no space to insert even compressed version of NVME support
3. This worked for me on an Intel drive
   
4. NvmExpressDxe_4.ffs was not sufficient to add boot support.
5. I extracted the 3 NVME support files from Asrock Z97 Pro3 and inserted them into 2.30 instead of NvmExpressDxe_4.ffs . This worked and both Windows and Linux can boot from NVME. 

As an initial caution, I disconnected all other drives from the motherboard. UEFI defaults. I'll add other components one by one.
