870A/870U-G55 Bad Checksum

i know i know, reset the CMOS. i did that. i reset the date/time...still bad checksum. replace with a battery that you know works from an older motherboard, same thing...
going to buy a new battery and try again... but if it still happens... why am i not able to clear the Bad Checksum error? is the board bad after 30 days brand spanking new?
EDIT: whoops. sorry bout that... *fires up Speccy*

This happend just suddenly out of the blue or did you do something (like performing a BIOS Update via MSI Live Update)?
out of the blue... i was playing an MMO, and my Windows Explorer reset itself back to default color (my custom color is red, it reset back to light blue)...and it ran the game slow. so i rebooted the computer, and bam, bad checksum. this was yesterday. been getting it ever since.

Any assistance would be appreciated.

Avoid using the OC Genie lite button??

Netstat not reporting input errors with packets that have bad checksums ?

Greetings,
Is netstat not reporting any checksum errors ? I have a number of Macs reporting checksum errors when sniffing the local net. I would think that these should be reported by netstat as input errors, or collisions right ?
But it doesn't currently. See below for sample, its occurring across protocols, tcp, and udp. Usually this error is a bad ethernet port or cabling, and sometimes a sw issue. Working on eliminating the switches, router, and dsl modem by doing more testing.
But is netstat broke ? I havent seen any errors from netstat since @ 3yrs ago.
length 64, bad cksum 0 (->f9fe)!)
One other question, can one monitor firewire 400/800 ports or usb with netstat ? Its not listed with man pages or netstat -h
Thanks in advance

Im am using two commands to view the data;
netstat -I en0 2;
(no errors in or out)
and tcpdump with the verbose -v argument
( reports the cksum ( these are CRC's right, not IP header checksum ? )
At the very bottom is the netstat -s output, otherwise a snippet of tcpdump ; replaced the IP's with xxxx's to protect the innocent
Thanks for your help.....

RMI over different subnets causing TCP BAD CHECKSUM

I have a customer that is trying to run my system over different subnets and is getting large performance hits due to a TCP BAD CHECKSUM error that they have been able to monitor when they have the RMI server on one subnet and the RMI client on another.
We don't see the problem on our systems (because we run on the same subnets) as do all of our other customers.
We've written a little program that just does some simple RMI calls over the different subnets and are still seeing the TCP BAD CHECKSUM errors.
Is there some reason that they are seeing these errors when the two are on different subnets? Is there any way to solve this problem (as it is causing a big hit in our performance)?

It is certainly nothing to do with RMI. The most probable culprit is bad hardware between the two subnets.

"Bad checksum in disk label" & "Can't open disk label package"

Hello,
I'm brand new to Sun/Solaris.
I have a Sun Blade 150, with SunOS 5.8.
I wanted to make a backup to prevent future data loss, so I put the disk in a normal PC with Windows XP to try to make a backup with Norton Ghost, the disk was detected, but not the file volume, so I place the disk on a desktop PC, and used Norton Ghost for DOS, the disk was recognized but once again not the file volume, so I wasn't able to make a disk backup, and I quit.
Put back the disk on the Sun Blade 150 PC, and then I was unable to startup the PC, showing the message "Bad checksum in disk label" and "Can't open disk label package".
What's wrong?
How can I solve this?
I need the data that's inside the hard-disk, so I cannot make a clean install, and i also don't have any install CD.
Thanks for any help,
JS

Thanks for the fast response,
i did't allow WindowsXP to write anythink to the disk, but somethink is written,and I don't know what. So now, the Spark-System dosn't boot from the HDD and the data on the disk is very important for me! When I format the disk all data are lost, right?
Is there a way to "rewrite" the Disk-Label-Checksum? I have an original Boot-CD-ROM, another HDD to install Solaris and so one, but I need the data of the corrupted HDD. And I also have not really a glue to use Solaris or any other UNIX, I'm a Windows-User.........

Slow file transfer between Mac & PC Network - bad checksums?

Howdy all. I've been having a persistent issue with transferring files from my Mac to my Win2003 server. The transfers are always much slower than they should be (compared to the PCs on the network with lesser connections), but even more puzzling, is that it will often go to 95% (or thereabouts) and then take twice as long to finish the remaining percentage as it did to transfer the vast majority of the file.
It's all gigabit from point to point and I've swapped patch cables, router ports, etc.. with a known good performing WinXP box to see if that would make a difference, but it didn't.
I've searched the forums and found some mention of mysteriously slow file transfers using SMB, but nothing conclusive.
I ran a LAN monitoring util on the Mac during a xfer and below is a snippet of the results from the log. No dropped packets, but lots of bad checksums?
Any help would be greatly appreciated.
Thanks,
Ed T.

While I have never tried it, Mac supports Firewire networking (TCP/IP over FW) and I know that some PCs do likewise. Mine does.
That being said, it's possible to link your Mac to your PC with a FW cable (both ends must be the large type of connector) and if so, you can transfer at 400 MB/s.
To enable FireWire networking on your Mac, in the Network preferences, at the bottom of the left pane, click the + sign and in the popup window, add Interface: Firewire.
As I said, I have never used it but in theory it would work. It's not at all like using the Target mode, this is a "hot" FW network link that can directly connect two computers.
IMO, it's worth a shot.

Satellite Pro U200 - Bad Checksum (ROM (Data Block) ) error

Hello when i start my Toahiba Satellite Pro U200
I have a Error
Bad Checksum (ROM (Data Block) )
PRESS ANY KEY TO CONINUE.
Pleas Help

The most common cause for "Bad Checksum" errors is the CMOS battery malfunction on the motherboard.
The battery could be empty or could simply be dead. But its really not easy to say whats wrong exactly!
Therefore I would recommend firstly to access the BIOS and to set it to default settings. Dont forget to save the changes.
Furthermore you should connect the AC adaptor and should let it connected for about 24hours to recharge the CMOS battery.
Maybe it helps to get rid of this error message.
If it doesnt help, then you should contact a notebook technician!

TCP bad checksum

Hi
Could someone inform me how a CSS 11500 handles a packet with TCP invalid checksum. I have two loadbalanced svrs behind a CSS and im seeing the and ACK with a bad checksum hitting the server VLAN interface of the CSS which appears to send RST 200 micro seconds later to the server but not to the client, Is this normal behaviour ?.
Thanks in advance

Stephen,
don't look at the interval with just the last packet.
The CSS will mark a flow idle if the interval between 2 consecutives packet is bigger than the idle timeout.
At that time, no reset will be sent.
But during the garbage collection process, the CS may reclaim resources hold by connections that were marked idle.
Even if the connection was not idle anymore, the CSS will destroy it if it was marked idle anytime in the past.
Moreover, for http connection, the idle timeout is 8 sec and not 16.
Finally, you can also check with 'show dos' to see if the css consider the connection as illegal - which would trigger a reset as well.
Gilles.

Malformed Packets and Bad Checksums

..I have a customer who uses MPLS to connect to all remote locations. The MPLS carrier has recently merged with another carrier, and they are in the middle of making changes to their MPLS network(s). As a result, some (but not all) of my customer's sites that have gone through these changes are having problems with one particular application only. Wireshark packet captures at the remote location and at the affected application server shows the following, among other things:
- Bad IP Checksum
- Malformed TDS Packets
- Malformed SSL Packets
- Malformed GSM over IP Packets
- Malformed ASAP Packets
- TCP Sequence out of order
- ACKed lost TCP segment
- Previous TCP segment lost
- Fast TCP retransmission suspected
This is only a subset of the problems that Wireshark shows. The strange thing is that only a subset of the remote sites are affected, and it really is only one particular application of a large suite of applications. All other applications work acceptably. In addition, other sites that have been converted work just fine as well. There are about 15 of 80 sites having thus problem. The MPLS provider of have reviewed their equipment and configurations. Unfortunately, after the changes were made, we have no visibility into the MPLS network (it just shows one hop), so I have no way of helping them to troubleshoot.
We have the ability to test the application using a site that is connected via Fiber, and the application works just fine. Of course, we have moved PCs, etc from site to site. The problem seems to stay with the site, rather than the computers.
Any advice or ideas on what I can do to test would be appreciated.

Jason,
there is lot of interesting troubleshooting to be done Yours is the type of case I loved when I was in the TAC as I enjoyed using creative ways to investigate and tackle similar problems.
there might be so many approaches for this that I have difficulties to list them all.
I am afraid that a CSC post is not the right place for that as this can be time comsuming and lot of effort is needed.
I suggest you to open a TAC case where you can find some engineer with the right mind set for this CSI type of troubleshooting.
cheers,
Riccardo

XCode 3.1.1 DMG download bad checksum?

Hi, tried downloading the new XCode 3.1.1 (Sep 12 08) twice now (with Safari and Firefox) and both times the DMG could not be mounted because the checksum was bad. Anybody got the same problem?

Hey, in case anyone gives a rat's a$$...as a follow up, I downloaded the .dmg again on a reasonably fast network, and this time around it mounted just fine... Must have just gotten corrupted along the way during the horrible painful and slow download the first time around.
Lesson to be learned: before sounding alarms, one ought to try downloading things on non-crap networks to minimize transfer problems first.

Sometimes the computer boots ok, and everything works great.
Sometimes it just doesn’t boot, it just gives a blank screen. So, I press reset and the post gives the CMOS CHECKSUM BAD. F1 to setup F2 to default.
If I go to the setup everything is just like I left, including the time. Even if I setup the bios with default configuration, the problem continues.
Here is a list of everything I have tried
1) Replaced the battery 2 times. I checked with a multimeter. It’s 3V allright
2) Disconnected everything leaving only 1GB memory and the graphics card
3) Updated the bios version several times, to make sure I did it ok. I cleared the CMOS after allright
4) I read every post in this forum about bios and P6N SLI Platinum
5) Already checked the D-BRACKET. It shows 4 green leds when the screen is blank
6) Already checked fans: CPU and graphics fans works ok
7) Already tested with memtest86+ V2.01
8) Already upped the northbridge to 1.325V, CPU 3 notches and the memory another 3 notches.
So anyone has any ideas, or I’ll just have to go to a computer store and swap the graphics or the PSU and try to see if the problem vanishes??? It’s gonna be tough… they don’t like to let you test the merchandise….
PS: Thanks for all the help so far that you have been giving to TheGimp, after all, we have the same problem…

I had the same problem after ~8months of trouble free service; it was intermittent too. sometimes it would boot fine, others times i'd get the error message. I removed the battery to test it. it was fine. i cleared the cmos with the button while the battery was removed. i noticed that the battery holder seems not to be anchored to the board at all. I haven't confirmed this but it looks like the protruding metal clip holds it all together. i had contacted MSI support about the problem earlier. they told me to clear the cmos. i asked about the battery holder not being secure on the board, and, as in the typical support response to an unusual question, they gave me some vague, undecipherable response. So, anyway when i put the battery back in, i felt the holder kind of click into place. I haven't had any problems since.
