I have a Dell Laptop 17RSE 7720 that I cannot Flash the Bios on. I have not tried to do it using Dos. I get Error 216 or 105.

nice a full model stated, rare here. NO OS< windows 10?
Windows, 10 ,removed the DOS mimic DLL files so now we must use freedos if DOS is needed, so I ask OS used above.
No reasons stated, the Intel processor venerability issue? what ?
or hacking BIOS , the possibles are ENDLESS. DYK
did you use F12 sandbox install
or did you make USB with freedos on it.

why not go to dell first and not fixya we are not dell.
do not flash BIOS until you learn the risks, did you?>
do not do that, unless you:
1: must, (have real compelling reasons to brick a good working perfect pc, (repeat 3 times for effect). oops....a daisy.

2; make 100 % sure the flash binary you get matches the exact service tag model PC you own , i bet you did not ask Dell to tell you that exact file that matches what you own.
I think but am not sure(dell has decompression locks on the file)
but I think they have more one ROM binary inside thee 10MB file.
but be nice if they said that, (their lil secret)

DID you used F12 mode? to update?
and from what version to what version.?????

3: Dell does not have what I call EZ_flash, that is using BIOS to flash itself. (super safe way, if power is good) Dell runs scripts at next boot to load bios binaries, in sand box , F12 way.
the EXE file there:
I always look first, I trust no one, on any binaries.
the exe passes virustotal and malwarebytes.
But the exe is locked, out. (decompression)
I think I know why (UEFI rules again)

5: is your PC set up with UEFI BIOS?
and safe boot? off
bitlocker suspended?

why not talk here at dell on same topic.
why leave DELL>?

One more problem. UEFI is H3LL
most makers OEM now block regression paths of bios.
so are you regessing ? trying to load, older BIOS version
you cant in most cases. did you? no before after stated. versions.
also learn that many PC, they upgraded UEFI like 10 times
and some you must do step by step, never v1 to v10 ok?
or it fails.

now some faCTS ON LAPTOPS.
Dell does not use Ez-flash, sadly is the best there is, not used.
this method has no possible way to multitask and fail.
the second most safe is running DOS(freedos is free) HP does.
The third most safe way is windows sand box. way. F12 per dell
and 4th flashing under windows live, is totally wrong.
never flash on any preemptive multitasking OS, live. do not.
may tired, many died (bricked forever)

this version>?
Version Version 1.11.1, 1.11.1 Category BIOS Release date 03 Jul 2018 Last Updated 03 Jul 2018
The normal Dell way under w10 , it creates install scripts in a file on your
hdd (not bitlocker'd) and then reboots w10 to sand box.
then w10 runs in special mode,(no it is not DOS) and this mode
safely installed the flash binaries.
if this fails or the HDD is missing (lol) or has linux loaded, you didnt say, then you can do this.
The below from Dell uses the word DOS in lazy way.
its not DOS, ok> DOS is MS product, or DRI, DR.DOS
Freedos is a modern version of DOS that runs on new hardware the real DOS (MS) can never do. ok?
I am told dell uses the w10 sand box method (w7/8/10)
I see dell ended this switch, -writeromfile
you can not extract the rom file.

this makes FREEDOS disk boot on the USB.
did you do this?

Corrupt rar/winrar Archive

Maybe is uploading to the FTP site using ascii transfer type, once on the FTP connections, you should use binary type.

that is done with the command bin:

The following FTP Command will set the file transfer mode to BINARY (the binary mode transfers all eight bits per byte and must be used to transfer non-ASCII files). ) and display the information.
ftp> binary 200 Type set to I. ftp

I need help, my internet explora is not fonxoning

it depends on what operating system your using and how capable you are using DOS (command), in addition load my computer and where it says my computer in the address bar just type, and search firefox or chrome.

right the dos way try this,
in run (or search) type command or cmd,

when it loads type c: \
this will take you to c:

then type this

ftp (you will be asked to login)
(user name anonymous and password as password)
Then type
cd /pub/firefox/releases/latest/win32/en-US
then type
when switched to binary mode type
get "Firefox Setup 25.0.exe"
then after download is complete, (there is no bar and dos appears to be crashed but it's not just wait and then you'll get confirmation that the download is successful) type
if for any reason it says connection timed out or failed, just type quit and start again (sometimes you have a few minutes as an anonymous user, so be quick) (ps your not hacking)
ok now goto mycomputer and select your hd (c:\) the firefox setup 25.0.exe file is now there, double click and install, congrats you now have firefox installed.

try it out and see if it works, if it doesn't get back to me.

ps type everything as is CASE SENSATIVE, ie Firefox not firefox!!

If FTP in dos(command) wont allow connections then you have an internet problem

All the best

My home built computer rig asus p5n-e sli has an issue where any downloaded large compressed file (say over 2 gigs) is "corrupted" upon decompression. CRC errors and such. I've run memory...

If you are attempting to open the file from a network / modem it is likely the network either is encountering collisions or other errors during the data transmission. Note: if the file is being sent through a session such as FTP or Telnet it is possible that it may not be sent properly. If the file is a text file, the file must be sent as either ASCII or TEXT mode. If, however, the file is a program or non-text file, it must be sent as a Binary file.

Problem downloading files up to 100 mb

Well, here's a bit complicated, yet effective method that just might reduce your downloading headaches... Let's say you're connect to the Internet using a 28.8K modem and that your Internet service provider lets you telnet to their server. Of course, your provider's server can download files much faster, so the idea here is to download the file to their server at high speed, split it, and retrieve parts at the highest speed you can to your provider's server. Generally speaking, this method not only is a faster way to download files, but it is also a more reliable method since you'll be downloading many smaller files rather than one large file.
First, find out the FTP address of the large (larger than 16M for example) file that you want to download. For example:
Telnet to your Internet service provider's server.
From within the telnet session, download your file to your provider's server. Following is a "screen shout" of a sample file transfer on an UNIX compatible server. Blue/bold text represents your input.
ftp> open
Connected to
220 ftp x.cpm FTP Service (Version 2.0).
User ( anonymous
331 Anonymous access allowed, send identity as
ftp> binary
200 Type set to I.
ftp> get
200 PORT command successful.
150 Opening BINARY mode data connection for
226 Transfer complete.
ftp> quit
221 Thank you for using! Once the file is download to the server, the next step is to divide the file into smaller pieces so that you will not waste too much time downloading should your Internet dial-up connection go down.
split -b 2000b
You're almost there! Now simply log off from your telnet session and start downloading (from your provider's server to your computer) smaller files (not the which the above split command (on most UNIX compatible machines) created.
Once you have all the files, simply merge them and you got a good copy of the original If you're using DOS or Windows, you can merge files using the following command (assuming that (16000 byte file) was divided into 8 2000 byte files named xaa to xah):
copy /b xaa xab xac xad xae xaf xag xah
Don't forget to log back into your Internet service provider's computers and delete temporary files ( and xaa..xah) once you've made sure that your downloaded copy is in good condition. Doesn't sound like the above steps could make your downloads faster or more reliable? Well, in most cases it does; specially if the file you're downloading is rather large. The reason why this method could possibly be faster is because you can download files from your provider's computer to your computer faster than from most remote sites. Of course, the reason for reliability is that downloading many smaller files makes it possible to resume a download without wasting as much time as resuming a larger file download would.
You can use FRESH DOWNLOAD.Fresh Download is an easy-to-use and very fast download manager software that turbo charges downloading files from the Internet, such as your favorite freeware/shareware, mp3 files, movie files, picture collections, etc. Unlike any other similar utilities, this software is 100% free, no charges, no banners in the software (whichsteal your bandwidth), no spyware.

Cannot upload pictures to an ftp site

You would open ports 20 and 21, and that would allow FTP transfer in passive mode. (Windows DOS FTP client does NOT do passive mode - so don't use that for testing)

In what way? FTP sessions are controlled by you and the input you place into the CLI (Command Line Interface).. Here is a page with the basics, on how to create a session and the commands to use to manipulate it:

SCP problem

What have you done to resolve this issue since your post? My instinctive knee jerk reaction is that the FTP format was incorrect. Meaning, an FTP'd file can be set for either an ASCII (7bit, 8th bit being used for error control or internationalization (extended character sets or codepages) OR a binary (all 8bits are significant) transfer. My guess is one of two items, either the wrong FTP parameter was supplied (or defaulted) in the transfer which corrupted the file, OR the FTP server re-interpreted the FTP file which stripped off some bits. Either way, you are left with a non-functioning card and a file that doesn't actually represent the original binary file. I wonder if you had previously set a management address to your SCP prior to this, or is this a newly powered up card? My first thought would be, if the card doesn't come out of "test" mode in one hour, I'd remove it, let it rest a few minutes, then reinstall. If the "test" led keeps flashing, I'd hook up your PC (and serial port) to atempt communication via the management address web interface(assuming you had set an IP earlier). If no communication occurs, I'd try to set an IP via the CLI, despite the "Test" flashing. Then attempt the web interface. The chances of this working are slim, but hey, you can't make it any worse. Otherwise, your only other option is to call Paradyne at 1-800-870-2221, (since they can burn you a fresh EEprom) ZT3000 "Beta tester of "0"s and "1's"
