Just abandon the Warp boot manager and chainload your Warp 4 partition with GRUB. I do it. Here's an example grub.conf entry:code: |

| Another boot loader would be AirBoot; worth trying out if you still have problem with Grub. |

...No Software Choice subscription was needed. IBM, apparently, simpy wanted to integrate better Merlin with their newer LVM. Notwithstanding, niether Warp 3 client nor the server (SMP and otherwise) based on the Warp 3 kernel but marketed as Warp 4 Server, appear to be able to support LVM. When I retrofitted those former Warp versions, all I got were crashes. ...the doscall1.dll (during the booting process) appeared to be incompatible to begin with --or perhaps was symptom when in reality the os2krn was the actual cause |

| Good morning, my dear fan of Chewbacca! Today must be your lucky day (for LVM stuff, of course!). Thank you for refreshing my memory. I happened to be doing some time consuming task in one of my Debian Linux partitions until this late (or morning for others); I decided to mount my older storage partitions looking for a related issue that I will be doing in the future. There, in the expanded directory, were the main files that are needed for the LVM hack on Merlin. The files needed are expartcp.exe and expartw4.exe. Those are self executables that you need to expand SEQUENTIALLY (i.e. order matters) stated below (VERY IMPORTANT to allow the second expansion of files FORMAT.COM and OS2DASD.DMD to overwrite the ones initially expanded when the utility prompts you about it): expartcp.exe -d Note: the switch (or option) " -d " is simply appended to the respective self executable files to expand directory paths --in case there are any. After I recognized the needed files, all was "peachy." All I did was to do a search for their name on the Web. That is what I recommend that you do. Notwithstanding, the following few initial pages have a link to downlad them: http://www.scoug.com/OS24U/2002/SCOUG209.DOWNLOAD.HTML and the following linky will set you in the mood to begin your masochist OS/2 endeavor http://sysadminforum.com/t71550.html Elaborating about it, our friend from S. Africa can use the same information provided in this last post to learn about OS/2 instead of hand holding him by offering a bootable LVM solution --i.e., I am taking myself off the hook where I placed myself priorly. Cheers P.S. This is the Novell's OpenSuSE Linux equivalent LVM implementation: http://www.chingonazo.com/suseGuiLVM.JPG |

| Hi El Vato and obiwan, Thankyou both very much for your most detailed and extensive help Are there any advantages to using LVM? and also, is that got to do with the new/ish Journaled File System? Vaguely remember in the past that its quite different to using HPFS, FAT or remotely similar file systems. For interest - I've still got an old '82 XT that's still doing our companies payroll and accounting packages! Last upgrade was to Dos 5.5! With close on 30,000 invoices and weekly payslips all up to date in the last 15 years our small company been in business- its only used up 5MB of 20MB avail hard disk space- pretty amazing what they could do with limited space and processing power in those days... sometimes think they've gone backwards when I go to suppliers and wait for what seems an eternity for simple statement or invoice from their M$ Windoze apps. Anyway, All the best for the Festive Season You guys rock! |

| Might as well move my Airboot-Grub issue into this thread, and separate it from the hardware thread. Please note that I know nothing about Linux -.a bbs friend from the echoes, knowing of my desire to avoid M$ if possible, and having read my lament of not having all the plugins I'd like for eCS browsers, sent me CDs of Ubuntu 5.10 last year and suggested I try it. After a long thread on installing it, after checking it out on the Live CD which makes no changes to my system, I tried to install it to my slave drive. I told it to use that drive for the install, and all seemed to be going well, but then it reported that it was installing Grub on the master drive, and I had no way to stop it. That killed my main eCS boot partition, and scrambled the partition table on the drive so I couldn't access the second eCS boot partition (a clone of the first) or the rarely used Win98SE partition, and Grub did not recognize either as installs of other OSes. Jan van Wilk eventually was able to send me a DFSEE script to restore the partition table, but then I discovered that all the data on that drive had been scrambled - tried to boot eCS from the second partiition, but the boot was not successful, and on the reboot, Chkdsk was finding problems with seemingly every file on the boot partition and data partitions. Trying to boot Win98SE also was fruitless. Fortunately, I found a working set of Fastback crash recovery disks, and, after I reformatted the master drive, I restored eCS from the backup I'd made just before trying the Ubuntu install. All was well again with eCS (Win98 was gone, but WinXP was recently installed in its place, for my occasional boots to it.) While the master drive was hosed, my friend disconnected it temporarily, and we installed Ubuntu, Grub partition and all, on the slave (I used Thunderbird for Linux to communicate with Jan and a few other people whose addresses I remembered - I normally use MR/2 ICE for e-mail, so I had no Thunderbird experience.) Anyhoo, this is how the situation currently stands - eCS, WinXP, and lots of free space on the master drive, Ubuntu 5.10 and Grub on the 20 gig slave, and Airboot as the boot manager. Airboot finds the two eCS boot partitions and the WinXP partition (which I had to move to enlarge using DFSEE - XP takes up much more disk space than 98. Airboot still lists it as the third partition, I guess because it's the third primary partition), and recognizes the Grub partition on the second drive as Linux, but when I select that partition to boot, nothing happens. The Airboot web page says Airboot has Linux kernel support from Fat 16 partition. The Grub partition is ext/2, so I presume that's why nothing happens when I select it. Does this mean I need to reinstall Ubuntu, and somehow tell it to make the Grub partition Fat16? I have no clue. I know Ubuntu has had two upgrades since 5.10, so, if a reinstall is needed, I'd download a CD image of 6.06. I presume I'd have to download the advanced version, so it can be told to STAY AWAY from the master drive? How would I do an install to the slave drive to make Linux bootable from Airboot, and not have my the data on my master drive destroyed again, other than doing the install with the master disconnected? I'm extremely nervous about Linux since the first disaster. Thanks as always for any help.

| I can't blame you for being wary of Linux after such an experience. I am so glad you had backups. I don't think Ubuntu will make a fat16 boot partition, but that shouldn't really be a problem. The latest stable Ubuntu is actually 6.10. Upgrading to the latest version would seem a good idea. Unplugging the master drive to install is ok, because I can help you manually install Grub afterward. The alternate install CD might actually work with the all the drives in place though, and save some trouble, because it claims to allow installing Grub to other locations. Unfortunately the documentation is incomplete on the procedure, and I don't have time to try it out. See the boot partition by default is not bootable, because the installer puts Grub on the MBR instead. What you want to do is tell the installer to install Grub not on the MBR but on the boot partition. That way it will load when AirBoot boots that partition. By using the "alternate install CD" at least you can tell it not to do anything, to avoid damaging your master drive. If it is not clear how to install Grub to the boot partition in the installer, just select not to install a boot manager, and I will be glad to help you manually install Grub. |

| Just wanted to bring this back to life, in case anyone has figured out an answer for me. I still have the 6.06 alternate CD (if I get 6.06 installed, I figure Ubuntu will tell me there's an upgrade, and let me download and install it.) The Win98SE that was destroyed has been replaced with WinXP, which turned out to almost fill the partition, so I used DFSEE to move the partition and resize it from 3 gig to 10 gig - Airboot still found it, so I can boot eCS or XP, but still not Linux. So, what do I do? The 20 gig slave with 5.10 remains unaccessible from Airboot. I suppose if I tell the bios to boot from the slave, Grub will appear and send me on to Ubuntu Linux 5.10, which will then tell me to upgrade. Would doing this and allowing it to upgrade only touch the Linux drive, or would Grub again be installed on the master and screw things up again? Or would Grub see the other OSes on the master and a) know to leave that drive alone, and b) add the two OSes to its menu and allow me to boot eCS, XP. and Linux? Does Linux have to have Grub to boot, or could I just install 6.06 on the slave without Grub, and either use Airboot or try to learn IBM's boot manager, which I'm told can be installed anywhere on the master drive, thus it wouldn't harm my eCS boot partition, which is at the beginning of the drive. Thanks as always for any help. As I said before. since my first experience I am very afraid of playing with Linux, though others who know more seem to do so without killing their systems. I really want to see what Linux is, though I am clueless about tar and all that stuff. Important note, in case this was missed - while my master drive was hosed, I did have my computer fixing friend disconnect it (I'm disabled, so I couldn't), and installed Ubuntu 5.10, Grub and all, on the slave. I had to install it, as I needed Internet access to converse with Jan about DFSEE and what he'd suggest. I used Firefox that came with Ubuntu, and added Thunderbird for e-mail. |

Sorry, I was waiting for you to try installing with the CD, taking care either to tell it to install GRUB on the Linux partition or not at all, and post your results. I can only advise after either doing it myself or reading what happens when you try.
I can't tell you exactly what the installer will do. My suggestion is to boot to the Alternate Install CD and from there either upgrade or let it destroy Ubuntu 5.10 and install v. 6.06. I think this would best be done with the drives setup as they are, the way you intend to use the system. It is supposed to let you put GRUB where you want. There is no harm in backing out of the installer to post questions about it if you are unsure. As I said before, moving the drive to the master position can be done, but only for copying the operating system to the drive. It would almost certainly have to be reconfigured in order to boot properly after it is moved back to the slave position.
IBM's BM won't boot Linux without a bootloader like GRUB. I don't know about AirBoot. GRUB really would seem to be the best choice for this application, the problem for you is with the interface to it provided by Ubuntu's installer.
I don't blame you, but again in my opinion the problem you had was with the Ubuntu installer. |
