Is it possible to install 2 kernels ?

I have following questions about my newly installed arch system.
1. Is it possible to have 2 kernels ? So that i can test the new one and then get rid of the older if I find the new one stable.
If yes, please point me to the documentation.
2. If it is not possible, how can I avoid  possible system breakdowns due to the untested (untested only for my system) kernel ?
thanks & regards,
Hardik

1: Yes, if each kernel has a differnt name. You can either install another kernel like the -lts one, or you can build your own custom one with a different name. To do that, search on the wiki for "Custom kernel", the wiki is a very good resource.
2: Also, if you don't want to go that far in case of something going wrong you can reinstall the older kernel from your cache if you haven't cleared it. To do that you would boot the live cd, chroot into your installation, then issue a pacman -U on the old kernel package. A tutorial on how to chroot into your installation can be found on the wiki page for dealing with kernel panics: http://wiki.archlinux.org/index.php/Kernel_Panics

    Hello Jan,
    All supported platforms for IBM hardware can be found at the location SAP on Linux and this points to SAP note 171380.
    You can contact IBM for older Blade / xSeries/ Netfinity models not listed under the above URL as mentioned to confirm if supported for your planned OS install.
    Information about supported combinations and install procedure can be found at the following sources:
    SAP on Linux -> Supported Linux kernels & Supported Linux distributions.
    SAP note 407314 - Released operating systems SAP R/3 kernel 6.x ORACLE, this assumes you will be installing with Linux.
    SAP note 171356 - SAP software on Linux: Essential information

  • Possible to install arch on a system with Broadcom wireless?

    My netbook has a broadcom BCM4313 chipset. Kernel module: brcmsmac. The latest arch installer can't properly configure my network and I don't have a wired connection at this location. The system keeps spamming messages like this on the terminal every few seconds:
    ieee80211 phy1: wl_ops_bbs_info_changed: qos enabled: false (implement)
    ieee80211 phy1: brcmsmac: wl_ops_bss_info_changed: disassociated
    ieee80211 phy1: wl_ops_bbs_info_changed: arp filtering: enabled false, count 0 (implement)
    Is it even possible to install arch linux on a system with a broadcom chipset? Or is the kernel too old, should I use another module?
    Thanks for your help!

    treadlefish could you post the wifi info from "lspci -vnn"? Then I can check if we have the same card.

  • Is it officially possible to install a USIM HSDPA/GPS module on my TX2-1014AU?

    Hi,
    Is it officially possible to install a USIM HSDPA/GPS module on my TX2-1014AU?
    As a wonderful multi-touch notebook, it will be perfect to be able to use GPS and having a USIM HSDPA on it without having a USB dangle hanging on it. (Its wonderful but abit heavy and hard to handle~)

  • Is it possible to install previous TRIAL versions of previous versions of Adobe Creative Cloud Software?

    Look, I'm just testing the trial versions right now.  Don't try to troubleshoot something that I don't ask; this is what I'm looking to accomplish:
    Is it possible to install a trial version of any of the Adobe Creative Cloud software in a previous version?  By that, I am referring to the following:
    I want to install a trial version of Adobe Premiere Pro CC 2014; NOT Adobe Premiere Pro CC 2014.1.  If you notice, I want to reinstall a trial version of the previous release.  Don't ask why, you'll just laugh for my stupid reason, but I'm merely wondering if it is possible.  Creative Cloud now only offers trials of the newest versions, and I want to install trails of previous versions for my own, personal reasons.  Is this possible to do with creative cloud, or must I do it some other way?
    Is it also possible to obtain the physical installation files so that I won't have to always go through creative cloud to download them again (and then I can just set it up without being connected to the internet)?

    The previous version option is only available to individuals which have a membership.  The availability of previous version titles available is dictated by the computer meeting the minimum system requirements and the entitlement of the membership to access the requested applications.  To future viewers of this discussion if you are unsure what software titles your membership is entitled to please contact our support team directly at Contact Customer Care.
    Wastingyourlifeaway you can download the installers for the CC version of the applications from Download New Adobe CC Trials: Direct Links (no Assistant/Manager) | ProDesignTools.  Please make sure to complete the Very Important Instructions prior to scrolling down the page and clicking on the download link.

    hello Dahveed, thanks for your reply, i solved it with the help of the migration assistant from another mac - now it works (but before as more info: for my new imac it was not possible to install apple remote desktop from appstore (the install-button not available, the same as installed already...) - and i don't know why...? - is it possible that the reason is the number of owned macs?)

  • Is it possible to install CS5 or CS5.5 on a 2.4 GHz Intel Core 2 Duo 4 GB 667 Mhz DDR2 SDRAM MacBook Pro running 10.6 (Snow Leopard)?

    Is it possible to install CS5 or CS5.5 on a 2.4 GHz Intel Core 2 Duo 4 GB 667 Mhz DDR2 SDRAM MacBook Pro running 10.6 (Snow Leopard)?

    Hi Carolyn, thanks for your quick reply. First thing I did before posting my question was to check the system requirements for Creative Suite, both on Apple and Adobe's websites. But I am however confused about the difference between "Multicore Intel processor" vs "Core 2 Duo", and keep hearing stories about CS5 not working properly.

  • Is it possible to install an SMTP proxy that will handle splitting group mail?

    I am running OS X 10.9.3 with Server 3.1.2 on a Mac-Mini Mid-2012. I learned on my last implementation of OS X 10.9.3 that Mavericks sometimes has issues with handling group mail.  As I rebuild my network, I am wondering if it is possible to install a SMTP proxy that can receive, process, then forward mail on to the primary mail server.
    For example, if mail is sent to a group account, this SMTP proxy would repackage the message as a message to a carbon copy list of all the group members, but if the mail is sent to a user account, the mail is forwarded unmodified.  Like this:
    As an alternative to this, I would also be interested a solution in which the Linux Mail Server referenced the Open Directory for account information, including password authentication, so that if a user in the Mac Network updates his password, that he can use the same password to access his mail on a webmail client or via the Mail.app.
    This is a callout for discussion points, ideas and recommendations. There is no problem here to fix necessarily.

    I am not aware of a tool to do the group splitting for you, this is normally the responsibility of the mail server itself.
    However with regards to your second query, a lot of people use a product called Kerio Connect instead of Apple's Mail server. Kerio can run on the same Mac server but in general is a far more powerful mail server. It does include the ability to authenticate user accounts against Open Directory.
    There is one issue you need to be aware of, like nearly all mail servers it uses the 'username' as the main email address, so if you want an email account of [email protected] then your Open Directory short name need to be jsmith, if you want your email address to be [email protected] then your user short name needs to be john.doe and so on.
    Note: While I have specifically talked about Kerio most other mail server including those for Linux would be able to link to Open Directory via LDAP and authenticate email accounts. The same link between email address and short name would usually apply.

The battery pack is unavailable as it was left behind when she came here for the summer. Is it possible to install the BIOS update with out? Is there a work around?
    Thanks for your time.

  • Possible to Install Leopard on External HD and Boot on Another Mac?

    Is it possible to install the Leopard upgrade DVD onto an External HD, AND THEN use the external HD to boot Leopard onto another Mac? Also, since the upgrade disc is an "upgrade," would I have to first install Tiger onto the External HD?
    If possible...
    Am I able to create an External Boot Drive that can boot both onto a PPC Mac and also onto an Intel Mac? Or will I have to create separate partitions?
    Lastly, can Intel Macs boot from an External USB Drive? Or are FireWire Drives required? Thanks!

    Yes, you can install on an external drive and boot the Mac. I do it all the time.
    I'm not 100% sure whether the same drive can boot PPC and Intel Macs -- I don't think so because PPC macs require Mac formatting and Intel Macs require GPT formatting to boot.
    Intel Macs can boot off both USB and Firewire external drives. PPC Macs can only boot off Firewire external drives. In any case, Firewire is better as it's quite a bit faster.
