Windows blocks access to hardware I/O ports, and the usual languages used for application programming don't include commands to accomplish this. In the modern systems this is done by a driver, which handles all the low level hardware stuff and exposes the results to Windows for an application to use. Check MSDN for the Windows DDK, if it's still available. If you're up to the challenge you can write your own. Personally, I gave up being that smart years ago...

my coworker and I are having similar problems. He recently bought a USB wireless device (linksys) and was trying to connect to the Net in his house.
Although it looks like he is connected (IP address and signal strenght look good), he cannot get onto the Net. His home-base station is running XP. His laptop is running Win2000. He has tried another XP with success.
Likewise, I have problems from time-time accessing Wi-Fi at public hotspots. I have a Belkin 802.11b network card. I am running an old Win98SE. Majority of time I can connect. But sometimes, I get good IP and signal, but same inability to access the Net (this is random and usually a Restart/several tries resolves this.)
Is there some setting or configuration we should be looking into? Default (hard code) IP addresses?
Puzzled,
Johnny

If your colleague is running his router in the default Wi-Fi configuration, he might want to try using a different channel and disabling all manufacturer-specific "enhancements".
Otherwise, I just would not trust the signal quality indicator in either Windows or the packaged software:
I had the exact same problem. My connection would stall from time to time, throughput was unacceptable, connection broke several times. I constantly had an indicated "excellent" signal quality. Moving the AP a few meters solved that problem. A friend of mine came over with some quality measuring equipment: The phone base station was interferring with my connection.
Cheers,
Sebastian

yuuuuhoooo ,
another LINKSYS isssue . i think sebastian had picked up very goood point about channel...most of the time it shoud work ...but just in case if no go ... follow these steps :
open LINKSYS set up page
in wireless tab---
1)put the channel as 11
2)change ssid---make it as simple as u can ---abcdef
3)disable the wireless security
go to advance wireless settings :
4)make becon interval as 100
5)RTS : 2304
6)fragmentation :2304
7)DTIM : if 1 select 3 , if 3 select 1
8)Frame Burst: Enable
make sure every time u make any changes in any page ---click on save settings
if its the router settings issue -- yr problem is solved
if still no go --- we need to upgrade the firmware for the router from LINKSYS site....![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

My guess is the DHCP server on the router is still enabled and is telling the clients that it's the default gateway onto the internet. Which is to say the LAN IP of the wireless router is being set by it's DHCP server as the DEFAULT GATEWAY to DHCP clients. This isn't true. The default gateway should be the LAN IP of your DSL/Cable modem. Tell me the LAN IP of your wireless router then do an IPCONFIG /ALL on one of the affected machines.
Please note if you are cable connecting your LAN into the WAN port of the router and your LAN and the wireless router are on the same subnet your dead in the water. If your LAN from the ISP is 192.168.0.X and your wireless routers LAN is 192.168.0.X nothing will work for the wireless LAN side. They need to be in different subnets. 192.168.1.X as an example.

I've decided to go mobile and get a laptop. I'm fed up of being hidden away in my room while my girlfriend is watching telly etc.
I plan to have VS2003 and Access 2003 installed on it but I dont want to spend too much. What is the minimum processor you recommend (I can always add memory later)

If you are still looking, I'd get something at least with Core 2 on board. Have good amount of ram, too.
Just a quick thought.

I'm not in such a good mood right now, my HD has just burnt out on me 
Everything was working fine until I tried to install VS inside a VMware virtual machine located on that drive. With no warning at all, it dissapeared? Thinking it could be a bug in vista I tried a reboot, but then the BIOS froze at the "Detecting IDE drives" stage. So I can't even boot up while the drive is conected
The drive is a Maxtor 80GB IDE 7200, only 3 years old. Does anybody know what may be wrong with it or how I could repair it? The drive itself is not that important, but there are a few files on it I would not like to lose if it can be helped.

If the system won't even POST with the drive connected, it's toast. There's pretty much nothing you can do with it, unless you want to spend a lot of money and send the drive to a data recovery company.
Well, after a little more thought, you MIGHT be able to find an identical Maxtor drive and POSSIBLY swap the PCB out. That might get you back up and running...possibly...maybe...

Thanks. I don't know exactly what the problem is, but I placed it in a USB caddy. This allowed me access to the files but I keep getting random I/O error's. I recently upgraded my main board to an ASUS M2N-E, which only has one IDE channel. So I have been meaning to replace this drive anyway.
Find an identical you say, funny, It does have a twin. I bought two of them, but the other has so far not shown any signs of problems. But then again that one sit's in the caddy and rarely get's used.

Just be aware that by breaking the clean room seal to swap PCBs your second drive will be left in terminal condition as well. If you do this, make sure you've moved all the data off it first.

I understand. But for an 80GB maxtor it's not really worth it. I will just try part-ex'ing it for one of the latest models.

I hope you did NOT mount the drive into the VM. Never do that if the drive is also known to the host. It does not even have to be the System Drive in order to cause serious trouble. Your description (one IDE channel, other drive on USB) sound like it was the System Drive, though.
If you mounted a disk-file, it SHOULD have worked.
In order to see if its just a Windows problem, I would boot the PC using a Linux LiveCD (if one Windows flavour does not recognize it, BartPE probably will neither). Then try finding the device (i.e., start QParted, cfdisk or whatever partitioner your LiveCD offers). If it does not appear there, either, you could still try to low-level-format it from the BIOS, if it is listed there.
Low-Level formatting will cost you your data, though.
If it IS listed in your partition editor, watch if the partition table is listed correctly and if the BOOT-flag is set on the correct partition. Fix, if necessary, then try again.
If all fails, scrap it.
Cheers,
Sebastian

Yes, I mounted the drive into VM, but it was not the system drive. The drive in question was my old system drive before I changed my MainBoard. I used to have two IDE drives, but my new board only supports one IDE cable, with my DVD-RW I had to move one drive to a usb. At the same time as updating I also bought a SCSI to be used as the system drive.
Anyway, that IDE drive was a spare. I have been using VM for a few years now and never had problems while mounting drives and sharing them between the host and client. But, I did recently upgrade to a newer version of VM, so that could very well be the problem.
The drive seems to be working ok now, and while it is I'm going to sell it. I just got another SCSI, so really, it's of no use to me.

can I tell if my hard drive is good or not (at least capable of spinning) while I am still trying to figure out if the motherboard is bad?
And when you say power it up the motherboard, do you mean only leave the cable between PS and the motherboard? what should it happen?
Thanks,

If the drive spins up on the new power supply, then it spins. That doesn't mean it works!
mhp130 wrote: And when you say power it up the motherboard, do you mean only leave the cable between PS and the motherboard? what should it happen?
Yes. The machine should startup and you should see the Power-On Self Test (POST) as you normally would. If you don't get anything, not even any beeps from the speaker, the MoBo is dead and that new power supply isn't going to do you much good.

Thank you so much Dave,
I think I am getting to the end of this. Unfortunately, the verdict so far is PS and Motherboard are both dead. Even this is quite fun with you guys helps, I am about to wrap it up. I am going to shop for a smaller size PC and if the HD(ATA) is still good mostly likely it won't fit in the newer PC's case. Anyway I can still use it(eg externally?) . Appreciate you guys helps.

Unless you buy a case for a miniITX board (square, only as long as the backplate connectors with a single PCI slot), any case you get will have space for 3.5" drives. The switch from parallel to serial interface did not change the physical size at all.

I recently purchased an HP DV-8000t laptop, nice box and am thiking about installing Vista on it,which led me to the thought, why don't I just add a new HD, Vista on one, XP on the other (just in case....) HP web site indicates you can clearly do this with this model, but they are very vague about what/how. They suggest calling some 800 number for a "bracket" and a disk.
When I asked do I have to buy this disk from them they said no, but make sure you get a 4200 RPM disk. so the question is this:
Do you think there is a real good reason for this or can I get a 5400, or 7200 for a whole lot less someplace else other than HP.
The second question would be what is this "bracket" they mention? and would it also be easier/cheaper to get someplace else?
Thanks
Mike

just a guess, but the bracket's probably used to secure the drive in the laptop. If you're not planning to switch regularly you can probably un/rescrew it every time. If switching regularly the bracket would probably make things easier. IF you can boot off of usb/firewire that would probably be a cheaper option. Id suggest trying to remove your existing disk to see what the bracket is actually involved in doing. I also have a very hard time believing the notebook won't talk to 5400/7200 RPM drives.

Hi,
I need some help here. I have a Compaq Pasario running celeron with XP professional. I was away for 5 days and my PC has been in stanby mode. After I came back, my PC does not responde to any actions - keystrokes,reboot,unplug.
The screen is out and the light is in orange. It does not take key strokes. The light on the pc itself is blinking green, I press and hold the power button(cold boot) and it still does not do any thing. I unplug the power cable wait for hours until the blinking green light goes away and plug the cable back again, the green light comes back and still nothing happens,
Anyone can give me some help what seems to be happening and how can I do about it?
Thanks,
|

Well, it sounds like you have three choices. You have either a bad processor, motherboard, or power supply.

I doubt it's a bad processor, because that wouldn't hold a charge big enough to keep the computer running. It could be the motherboard, though.

Well, his description of the problem amounted to "turn it on and nothing happens". After doing this crap for over 21 years, I can tell you that a bad power supply, bad BIOS, bad motherboard, AND a bad CPU are the possibilities.
BTW, putting a suspected bad power supply into a known good PC is a bad idea. If the power supply blew the motherboard, you'll just potentially end up blowing another motherboard.
Testing the voltages comming off the power supply is the best option, but in the absense of a voltage meter, replacing the power supply with a known good power supply is the next best option.

Good point, I never thought of that.
