MPLAB IDE Works!
location: ubuntuforums.com - date: November 5, 2008
Hello all, I've just started with Ubuntu (2 months now) and was almost turned away while trying to use MPLABS IDE with the ICD 2 programmer.
After 3 hours and a headache to kick, I finally got the IDE running with Crossover. The programmer successfully works across the serial interface using a prolific USB to serial converter. It would however only work with the PICC PRO compiler, not the lite version, weird. I cannot get the USB to work still, and thats my next mission.
I've noticed a handful of people trying to use MPLAB software with Linux and upon failing have turned to piklabs. Piklabs is fantastic, however it has limited support for some microchips as it is still in development. So hopefully Crossover staff can add support for this product (MPLABS) and keep another handful of people interested in Linux.
EDIT: I've just realised ive posted in the wrong section. Terribly sorry
IDE vs AHCI ?
location: ubuntuforums.com - date: December 17, 2008
I'm a real nooby so be gentle...
I have a ASUS P5Q-E mobo (P45/ICH10R chipset) and had a hard time finding a linux distro that would recognize both SATA and PATA drives. Ubuntu 8.1 does that so I am trying to wean myself from XP Pro. Both OS are currently installed on separate HD in IDE mode. Apparently there is no significant benefit to non-RAID AHCI Windows so I am wondering if there is any benefit to moving my ubuntu to AHCI? If yes, is a re-install required?
Ubuntu = AHCI and windows = IDE
location: ubuntuforums.com - date: November 20, 2010
I am having this problem. I had a working, installed version of Win xp on my hdd and I just installed ubuntu 10.10 on a partition I had next to it. Now I guess back when I installed win xp I made it boot under IDE mode. And of course the grub for ubuntu only works in ahci mode.
How can I boot onto my windows partion to change the drivers to allow me to boot under ahci mode (I have seen tutorials on how to do this)? Because if I boot under ide mode my ubuntu grub won't boot and nothing loads
I really would just like to find a simpler fix rather than reinstalling my windows partition.
I have a gigabyte 880GM-UD2H mobo.
AHCI or IDE for Sofware Raid Setup?
location: ubuntuforums.com - date: November 26, 2008
I'm confused regarding the AHCI, IDE and RAID storage drive configuration in the bios setting.
I have an ASUS P5Q-EM. I'm building a headless fileserver using Ibex and Samba. I'm doing software raid 1 using two physical drives for the operating system and raid 5 using three physical drives for data storage.
In the bios, there is an option for AHCI, IDE, and Raid. All of my drives are SATA II (3G/s). I know Raid is for the onboard raid setup. Based on my other reading, software raid is better.
Which option would work best for the Ibex/Samba filesever, AHCI or IDE?
Thanks. Happy Thanksgiving!
BIOS IDE > AHCI = Ubuntu won't boot
location: ubuntuforums.com - date: October 17, 2010
I did a stupid thing (apparently), and am wondering if anyone has also done it.
Long story short, I changed these BIOS settings (and changed them back), but now Ubuntu won't boot:
SATA RAID/AHCI Mode: from Disabled to AHCI
Onboard SATA/IDE Ctlr Mode: from IDE to AHCI
The last thing it says is "Init: ureadahead-other main process (nnn) terminated with status 4". Booting off an Ubuntu CD and entering Rescue mode gets me to a shell; the file systems are still there, but...

Switched IDE to AHCI, no more GRUB?
location: ubuntuforums.com - date: April 14, 2013
I decided to switch the IDE setting in my BIOS to AHCI for potentially better performance. After changing it, my computer would no longer boot at all, even if I changed back to IDE. It hangs at "Loading Operating System...", so I do not even have access to GRUB at all.
I have tried using meijer.o's suggestion in this thread, as well as chrooting from a live USB into my system to update the GRUB, but I'm still stuck. Updating the BIOS didn't help either, currently at version F10a.
I have a Gigabyte GA-990FXA-UD3 revision 1.0 motherboard and a Phenom II x4 965 processor, and will post the contents of what fdisk -l shows me from the live USB as soon as possible. Thanks for any help given!
AHCI won't boot with six drives, IDE will.
location: ubuntuforums.com - date: March 30, 2013
I've disassembled my FreeNAS drive and moving the drives over to my ubuntu machine (12.10).
Pre-move: I had two drives. one system (750GB) drive and one datadrive (1500GB) on an ABIT IP35 PRO mobo. It has 6 sata ports on an ich9 controller. It also has 2 esata ports on a Jmicron controller (not used)
After-move: four more drives. maxing out the internal SATA ports. the computer halts where it should boot from a drive telling me that there isn't any boot drive. I've checked that the boot order is right. It doesn't matter if which 6 drives I'm using, I've tried with 6 different drives in the 4 spots that were left over before moving over the drives. I tried different cables. I've tried a different PSU. I've tried having a second PSU power two of the drives since I had my suspiciouns that it was a power problem. I tried with replacing two of the drives from the FreeNAS system to just make sure it doesn't try to boot from my ZFS volume which the four drives were part of.

AHCI prevents Grub from chainloading works fine in IDE mode
location: ubuntuforums.com - date: October 9, 2008
I am having an issue with triple booting OS X, Ubuntu and Windows XP.
Currently, I have 3 hard drives, all with their separate respective MBRs
C:\ contains the XP bootloader, with my NTFS partition, connected via IDE
H:\ contains Grub, with my Ubuntu partition, connected via SATA
N:\ contains Darwin, with my OS X HFS partition, connected vis SATA
Ok, so I initially just had XP and Ubuntu running, this worked a treat, I could chainload the xp boot easily. Also I could boot into ubuntu and that worked.
Next, I installed OS X on my N:\. I had to change the bios settings for my drives to work in AHCI mode, from IDE mode, as this is what is needed for OS X to work.
I had a few issues with grub and booting into OS X, I ended up copying the chain0 file into the /boot/grub/ directory to get it working because I couldn't chainload directly to the N:\, it just sat there. but that's now working with the chain0 file.
Now my next problem is that, from grub, I ca
IDE to AHCI without reinstall?
location: ubuntuforums.com - date: January 16, 2009
I recently built a computer with a SATA hard drive and CD drive.
My motherboard default setting is to have SATA drives emulate and appear as IDE, which i did not know when I installed Ubuntu.
My question is this: is there a way to switch the BIOS to AHCI mode without having to reinstall Ubuntu? If not, is there a way to reinstall ubuntu so all of my settings and files are still there?
GParted sees no SATA IDE drive, switching to AHCI not an option
location: ubuntuforums.com - date: September 3, 2008
I have a new Windows XP X64 machine that I want to turn into a dual boot. In the bios my SATA disk is set to ENHANCED IDE mode (since AHCI doesn't bring me much and the XP installation doesn't support it out of the box). Now, when I want to install Ubuntu 8.04 from the live CD no partition shows up when GParted is launched. I've read that switching to AHCI should solve this, but that is not an option since it will break my existing XP installation while it offers nothing extra.
What are my options?
