I'm not certain when they'll update the catalog, but I wouldn't be surprised if it's sometime shortly after the new year. I believe they update the catalog quarterly, but I'm not sure when it would have last been updated.
Hi, I tried to update the BIOS v.2.9.3 through the HTTPS server "downloads.dell.com" and it got failed. From the firmware update details, I could see, it tries to fetch the BIOS v.2.9.1 instead of BIOS v.2.9.3 from the repository. [IMAGE] Then, I manually downloaded the .exe file from the Dell site and successfully updated the BIOS v.2.9.3. Please let me know if anything missed when I update through the HTTPS server. Thanks,Naviyan.  
BIOS v.2.9.3 update failed on R740xd2 platform.
