Can't Boot from CD still K8N Neo4 MS-7125

I made several boot CDs, but am unable to boot from them.  I don't have a floppy.  I want to flash my bios.  I tried to read every post related to my problem but could not find a match exactly so that's why I'm  posting.
The error says
EMM 386 Address line A20 already enabled.
The other posts say to simply set the Gate A20 option to FAST.  I went through my Bios settings several times and don't have any kind of Gate A20 option to set.
Win Xp tells me my Bios is v1.0 but my Bios says my Bios is 1.5 and I'm trying to Flash to v 1.8.
I've tried everything I could think of.
Win Xp Home
K8N Neo4 MS 7125 Platinum

I don't have access to the Internet on my computer, I'm typing this on my friends computer.  I found a way to get around the problem though temporarily until I can figure out a way to create a bootable
CD.
My work around was this.  I created several boot CDs from several different software programs, none of them worked.  I tried Ultimate Boot CD UBCD. and there was an option called go to Dos level using Madboot.  I went to DOS level and tried running the flash utility on my C: drive but it came back with the message ' unknown file or program'.  Then I tried putting in a CD into the CDrom drive that I burned earlier with the files for flashing the BIOS and ran them from there.   Why didn't they run on my C: drive and only on my CDrom drive? I don't know, but it worked.
Thanks

  • Can't boot from external HD with Leopard on MacBook Pro or PowerBook

    I can't boot from an external HD with 10.5.5 Leopard on either my MacBook Pro or my PowerBook G4. I had a PowerBook G4 from which I could boot from either an external FW400 drive or an external FW800 drive. At some point, I stopped being able to boot from any HD, but I'm not sure if it was after upgrading to Leopard or not? Recently I just bought a MacBook Pro 15" and transferred all my files over from the PowerBook to the MacBook Pro during the install. However, even with the new computer, still cannot boot from an external drive. I have Leopard 10.5.5 running on both the external HD and the internal HD.
    Is this a common problem? Anybody know how to fix it?
    Thanks!

    That probably wasn't very clear was it? I have several ext. HD's, some with bootable systems and some just backups. One bootable disk was made with CopyCloner and the other was a clean format and only had an original install of the OS just to use for an emergency boot. They both booted just fine. Then at some point, they stopped being bootable. I have used the Control Panel "Startup" and also used the Option key boot and picked the bootable disk. Neither one boots anymore. It started doing this on the old PowerBook and then also refused to boot on the MacBook Pro. This is not the problem with the HD since it happens with any bootable HD. Something is going on at the system level and it was transfered from the PowerBook to the MacBook.
    Thanks,

  • Can't Boot From Install Disc 1 ?

    Holding down "C" at Start Up isn't working.
    Most of the time I can't get Preferences > Start-Up to even "see" my Disc 1.
    When I can get it to show up in Start-Up, and Select it, and Lock it ... it Still Won't Start Up from the Install Disc 1 ... and in fact usually ejects the disc.
    Sometimes when I re-push in the disc, I get the message that a Blank Disc has been detected, "what do you want to do with it."
    But, it shows up in Disc Utility, and when I run Verify Disc, it all looks good?!
    The Disc has Mac OS version 10.4.8 on it. I'm running 10.5.7. I'm all up to date with my software.
    Yesterday I ran the latest version of Disc Warrior. When I run TechTools 4.0 it seems to get stuck running Files. When I run Repair Permissions from Disc Utilities, it shows a fairly massive amount of issues. Running it over and over again doesn't seem to make any difference.
    I WANT to run my Install Disc so I can run Repair Disc from Disc Utility ... because I'm having a number of issues ... and I seem to get the spinning rainbow a lot.
    SUGGESTIONS ?! ... thanks ...

    Disk Utility that can repair a 10.5.7 permissions is only found on the Leopard installer disc. Tiger can't repair Leopard when it comes to permissions, and may also have difficulty with the directory.
    Secondly, if your MacBook Pro was purchased after October 26, 2007, it can't boot from any Tiger disc.
    If your MacBook Pro was purchased prior, you can use the disk, but you'll want to follow these directions for hardware diagnostics:
    http://docs.info.apple.com/article.html?artnum=303081
    Only if your MacBook Pro has Tiger installed, should you use Tiger for the directory or permissions*:
    http://www.macmaps.com/directoryfaq.html
    Macs can only boot from the operating system that shipped with them, and newer retail operating systems. This means:
    1. pre-October 1st, 2007 MacBook Pros can boot off:
    - - the discs that shipped with them
    - - retail 10.5 discs which look like * that do not say Upgrade, DropIn, or OEM.
    2. October 1st through October 25, 2007 can do #1, and also use Upgrade and DropIn discs. Those disks were offered as a limited time mail order Up to date program, some were dropped in the box that came with them.
    3. October 26th through November 14, 2007 can boot off the discs that came with them, and retail 10.5.1, 10.5.4, and 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    4. November 15, 2007 through June 29, 2008 can boot off the discs that came with them, and the retail 10.5.4, and 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    5. June 30, 2008 through December 14, 2008 can boot off the discs that came with them, and the retail 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    6. December 15, 2008 and later MacBook Pros can only boot off the discs that came with them.
    Presumably when Snow Leopard comes out in September, all of the above will be able to use Snow Leopard because of the specs on http://www.apple.com/macosx/specs.html

    My daughter's 13" late 2011 MacBook Pro has frozen (null sign displays) after Yosemite installation. I can, however, boot from a clone of my MacBook Air that is on an external drive. I reinstalled Yosemite on the MBP HD, but it still hangs in mid install. Despite the fact that I can boot from the external, could it be the RAM that's the problem? I'd happily put 8 GB in if it seems probable that would solve the problem. I've tried all the suggested procedures that I've seen posted here. Disk Utility, and my older version of DiskWarrior indicate the HD is OK. I have DiskWarrior 5 on order.

    Boot the MBP with the OPTION key down.  If successful, you should see two HDD icons,  Select the recovery partition (on the right).
    From the 4 option menu select Disk Utility.
    Run Disk Utility>First Aid, Verify and Repair.
    If the disk cannot be repaired, it will have to be replaced.
    Ciao.

  • Weird screen pattern freezes iMac, can't boot from HD or DVD

    I woke up today to find the screen of my iMac black with a sparse pattern of bright pixels on it. I wasn't able to power down holding the Power buton so I unplugged it and left it for a bit before plugging back in. I was then able reboot without any problems. Then a few hours latter a weird pattern appeared across my screen, kind of rolling, animated in spots as seen here:
    I powered down, started it up and the screen had this pattern on it:
    It froze during startup at the point shown in the photo with the Apple logo. I powered down, unplugged, plugged back in and then tried booting up from my Snow Leopard install disc. It also froze on the logo screen. Another attempt brought up the "You need to restart your computer…" message in different languages shown here:
    I figured it was having a kernel panic so I did some searching around and followed instructions on The X Lab - Resolving Kernel Panics page and Apple's Kernel Panic Troubleshooting page. I unplugged everything but my mouse (wireless keyboard) and tried booting into Safe Mode. The screen still had the same pattern but it froze again during startup, the grey progress bar having disappeared.
    I can't boot from my hard drive or from a DVD and the pattern is always on screen when I turn the iMac back on. I can't run Apple Hardware Test. I'm stuck but I'm wondering if anyone knows what the cause might be or has any suggestions on how to fix it or even get it to boot up somehow.
    I have TechTool Pro and a large flash drive. I'm going to try creating a bootable USB drive with Snow Leopard on it from this backup computer and try to get TechTool Pro on it as well. I'll report back but I'd really appreciate any feedback on this problem.

    Some things to report. First, the night before any of this happened, I noticed the fan was running when there wasn't really any reason for it. The computer was idle, no major tasks running. I'm wondering if perhaps the videocard overheated and is causing problems. Perhaps the temperature sensors are screwed up?
    Today I got a USB keyboard hooked up and reset the PRAM. Still unable to boot but the pattern on the screen did change from the mess of b&w squigglies above to vertical bars as shown here:
    Trying to boot normally or in Safe Mode both result in the spinning wheel freezing and halting startup.
    I found powering down then gets weird. It's like it tries to turn on again but can't after a second. Or sometimes it will and the mouse lights up, I can hear the optical drive but the screen stays dark. At that point I need to unplug and try again.
    I tried booting from Snow Leopard install DVD during one of these weird cycles and could hear it trying to access the optical drive but I don't believe it even got to the chime stage.
    I attempted booting from the install DVD again after unplugging. No luck there but instead of a frozen spinning wheel, it brings up the "You need to restart message…". Other methods don't do this.
    Still at a loss to find a reason for this but it appears to be a hardware problem, no doubt the video card based on the screen issues. Does any of this shed any light on what the problem is or (even better) how to fix it?

  • I can't boot from OS install USB drive Mac Mini Model 1176

    How I can't boot from OS install USB drive, Mac Mini Model 1176

    Thank you Eustace Mendis for your answer.
    I rebooted the Mac Mini holding the Option key down but it doesn't work. I used an USB drive with O.s 10.7 from Apple that I have used previuosly with other computers and I also tried with a CD install O.S 10.6
    It seems that the Mac Mini can't recognize the keyboard inputs and I tried with 3 different keyboards but still didn't work.
    I also reset the SMC and PRAM but I had no luck. Any clues?

  • Can't Boot from bootable CD/DVD or USB.

    I'm trying to install a new OS from a bootable DVD that I created. However, my T530 will not boot up from the DVD. I checked the boot order in the BIOS settings, and even explicitly tried to force to boot from my DVDROM usint the F12 boot menu. I've been able to boot from this DVD on my other computer.
    Any way to diagnose whether my DVDROM is faulty, or is there perhaps some BIOS setting to fix this? I am able to read the disc from Windows, just can't boot from it. The laptop is brand new, just opened it up today, so I don't know why something as simple as this wouldn't just work.
    Solved!

    Next, I copied the ISO image to a USB stick and tried to boot from that instead. But it hung. I was able to boot from the same USB stick on another laptop.
    All the signs seems to suggest the laptop is simply defective, which is extremely disappointing considering it is brand new and I waited for about a month to receive it.  Is there anything else I can/should try (some diagnostic utility, perhaps?), or do I just send it in for a replacement?  
    Is you used the tool at http://www.microsoftstore.com/store/msstore/html/pbPage.Help_Win7_usbdvd_dwnTool to take the .ISO file and create the USB stick, I'd say you are right and have an issue with the system.
    Did the system ship with Windows 8 and is safe boot turned on?
    Yes, it is Windows 8 with Secure Boot on by default. I tried it both with it enabled and disabled, and it didn't work either way.

  • Admin password changed - can't boot from CD

    I'm the sole user of my iBook, and the administrator password USED to be the same as my user login password. I have no idea what happened, but now it won't accept the admin password (it still accepts it as my user password), so I can't install new software or updates. I also can't boot from the install CD using the 'C' key - nothing happens, it just boots from the HD. In fact, I can't boot into any different mode by pressing a key at startup. I'm going crazy, I have no idea what happened or how to fix it. It's something that's happened since 5/20/06, because I installed 'dashcode' on that date. I also installed the 5/18 security update.
    Does anybody know what might have caused this, or how I fix it? Thanks.

  • I can't boot from OS X CD

    I need to boot from the OS X CD in order to reset the admin password however, I can't boot from the CD. I have tried changing the startup disk but on restart it still boots from the hard drive. I hold down the C key and still it boots from the hard drive.
    The Powerbook is running OS 10.2.8 and I am trying to boot with an OS 10.2.1 disk.
    What is the problem?

    Are you using the OS X installer disc that came with the computer? If not, be sure the version of OS X you have is a late enough version to boot the computer model you have. Since you didn't indicate exactly which model Powerbook you have, there's no way I can tell what minimum version of OS X you need.
    Note that if you have an Upgrade CD it will not boot the computer unless the version installed on the computer is earlier than the version on the CD.

  • I can't boot from Install CD

  • Can't boot from harddisk following fresh install, corrupts files

    Hello all,
    (Macbook Pro, Core 2 Duo 2.2, 4 gb ram upgrade, otherwise stock)
    So, this all started with the combo updater. I repaired my permissions and tried installing the combo updater for 10.5.7. It failed, saying the package it was installing from was corrupt. So I downloaded it again, tried again, same error. I figured I better restart. Kernal panic. Same for all subsequent restarts.
    Booted from Leopard DVD, repaired permissions, that worked, then tried to repair disk, failed, couldn't do it. Tried rebooting, still no good. Gave up, formatted the hard drive (Mac extended w/ journaling). Rebooted from DVD again (installer couldn't see the drive, odd) installed Leopard.
    But now every time I try to boot from the disk I get stuck on the gray screen. Reset PRAM, no good. Tried safe mode, it gets stuck at the same screen. And when I repair disk permissions I have new errors, and now it again cannot repair the hard drive.
    So I can't boot from the hard drive, and when I try it corrupts my disk. I obviously need some help from someone smarter than me, any takers?
    Justin

    I would try removing one stick of memory and attempting to reinstall. If it appears to work, add the other back and try to reboot. If it fails on one stick, then try the other. This way you can at least eliminate if its a HD or ram issue.
    It sounds like a drive issue, but swapping out ram is easy and can eliminate a lot of other potential causes of the problem.
    Good luck.

  • Can't boot from IDE hard drives

    Just purchased a barebones system with a KEN NEO Platinum board running an AMD 64 3400+. Tried to install old Maxtor hard drive (40 gb) into new system and a blue screen pops up for less than one second and reboots PC. I can’t read the blue screen but I believe it is saying there is a hardware conflict.
    What is causing this. The CMOS recognizes the HD but it can't boot from it. I’ve got two of these units and both have the same problems. I put the drive back into the original PC and it works fine.
    Need help desperately.

    When I connect the cables, they show which is the slave and which is the master. In the CMOS, everything looks fine. I've noticed alot of people are having difficulty installing used and new hard drives. I've been working with PC's for quite a while and I've never had this much trouble. I was hoping there was something I missed in the CMOS settings.

  • Can't boot from cd

    Just replaced a hard drive in my old G4 titanium laptop and it worked fine until I did the OS update. The first time i did the update and clicked restart, it would only go to a black screen. I reformatted and thought I would just say to he'll with the update and leave well enough alone. My wife used it for a few days and said it was really slow, so I did the update again. I selected one update at a time and when I did the Security Update 2009-005, it gave an error and said try the install again. I rebooted and now my dock has dissapeared and when I try and reboot, it does nothing. I tried to run disk utilities and the program will not open. I tried to reformat the hard drive, but when I hold the C key down to select the DVD to boot and install from, it goes back to my hard drive and just boots to the installed OS. I then tried to select the DVD from my preference start up disk option and there is no CD/DVD option to select as boot drive. I see the mounted DVD disk on my desk top and can access the files on it, but can't boot from it to reinstall. My install was Tiger full retail. The laptop came with an install disk that had Panther. Any ideas would be appreciated.
    Mark

    Thanks for your reply and yes I did try option as well, with no luck. I finally reformatted through FireWire and another laptop. I am now installing from the disk that came with the G4. So I will try Panther to Tiger even though my Tiger is a full retail disk. I am not sure why Apples up dates to 10.4.11 crash this g4, but I'll try for the third time and see what happens.
