It appears I cannot install Windows XP on a second drive without writing 30MB to the boot drive? The easiest solution to this problem is to do as another poster suggested: Remove all drives, jumper your WinXP drive as master and install WinXP on its own. Then re-arrange and rejumper the drives as you like, reset the BIOS settings to recognise the new drive sequence, and finally use fdisk to check that the WinXP partition is set with the active boot flag 'a', your grub.conf is as per the handbook for multibooting WinXP and your fstab is adjusted accordingly for the corresponding Gentoo and WinXP partitions. With regards to the Grub commands: The makeactive means just that, make active the current (WinXP in our case) boot partition. The rootnoverify tells Grub to not try to read the M$Windoze proprietary boot code (it can't). The map command virtually swaps drives so that WinXP boot loader does not go spastic if it finds itself on any other drive than /dev/hda and so overcomes the WinXP inability to boot from any other than the first drive. Finally there's the hide/unhide command which will allow multiple M$Windoze OS' to coexist independently without blending their partition bootloading files into a mess (the intended M$Windoze multibooting approach). Is it possible to safely shrink an ext3 partition on the current drive 0 to make way for this? You can resize an unmounted partition by running resize2fs to shrink the filesystem, then delete the partition in cfdisk and recreate it slightly larger than the new filesystem size and then running resize2fs again.

I doubt that this is necessary. Either try it with only one drive connected to the machine as suggest previously, or perhaps try this: Create your own NTFS partition and mark it as the only active boot partition on the drive you want it installed, using fdisk or whatever. Then use the hide command to hide all other OS from the grub menu. Then try to install WinXP to see if it will get on with the job. I am not sure that this method will work without any problems, because I haven't tried it out myself. I suspect that it may still fall over itself when it detects that the proposed partition is not a primary partition on the first drive. Truth is that by the time you changed your grub.conf to include the hide command, then re-installed Grub, remodified the grub.conf, etc. you might as well physically swap the drives and complete the WinXP installation as B Gates intended. I must reiterate here that every time you change the physical order of your drives you should reset your BIOS. This is a good idea even the BIOS is supposed to do this automatically. Also, when you finish installing and before you reboot with Grub may be worth checking that the grub.map file shows the correct mapping sequence of your devices. -- Regards, Mick -- gentoo-user@gentoo.org mailing list

Is there a speed difference between master and slave? Hi Neil, Assuming they are both the same speed drives (UDMA33/66/100/133) then there is no speed difference from the drive whether it is set as a master or slave. The issue, and it's a small issue, arises when both the master and slave are needed at the same time. In this case, even if the slave is in the process of sending a packet across the EIDE cable, the master can interrupt that packet and send it's own. After the master finishes the slave has to restart it's transmission which results in lower perceived bandwidth even though the bit-rate is identical. For this reason, in my systems, I place only a single drive on each cable and every drive is set to be a master. This then allows the buffering in the EIDE controller in the chipset to buffer the packets and put them on the PCI bus without any need to resend. I'm not sure any of this is measurable without setting up some pathological test case, but for instance if you were doing a bunch of compiles and watching a DVD movie at the same time, and assuming your DVD drive was a slave drive, you might get some artifacts in the movie. Anyway, thanks to all for the ideas yesterday. It appears that as the day ended, and being tired, I messed up my Gentoo drive somewhere in the process of shrinking one partition to make way for the Windows partition. The system no longer booted last night when I went to bed. Go figure. I didn't think I was even touching the boot partition. Today I have to restore that and then I'm going to pull all the drives except the one for XP, install Windows, and see then if I can get grub to start it up. Note that most brain dead part of this Windows installer (nahh...it's all brain dead) was that while the XP install requires that I have at least one 30MB windows-compatible partition on the primary drive, and while it will create the partition for me, it will not format the partition and is therefore cannot continue with the install. (An unformatted, free partition is not 'Windows compatible'!) How's that for forward thinking? This is Windows XP, not Windows 98. Dual boot has been around for years but they still cannot handle what they need for their own operation in that environment. Amazing...

Is that not true? You don't have to confuse a bootloader with Windows loader modules like NTLDR or stuff like that. If we're talking harddisk boot a booloader has to sit on the first sector of the first track (= MBR, master boot record) on the drive in question. When you boot a PC the last thing a BIOS does is to read the MBR and execute the code that is supposed to be a boot loader. The bootloader then will actually load an OS from a specific partition. BTW someone on the list wrote Windows bootloader needs to be on the first nfs/vfat partition on the boot drive and that partition must be active/bootable. That is not correct since even Windows bootloaders have to follow the rules. A bootloader sits in the MBR. At boot time (that's when the BIOS rules) there's no such thing like partitions.

Re: Re: [gentoo-user] Windows on a second drive?
It's been a long time since I did a multi boot Windows install. With Windows and the boot managers for Windows maybe it has to be. However, with Grub or LILO you set them up on the MBR, then tell them where to find Windows and it's all done from there. At initial boot there are no partitions.

Drive 1 - Via chipset - Gentoo Drive 2 - Promise PCI EIDE ATA-100 cont. - port 1 - GigaStudio audio Files Drive 3 - Promise PCI EIDE ATA-100 cont. - port 2 - Win XP Note that I have not actually installed Win XP here. I just took the drive from the old machine. That machine was a Via chipset and so is this one. First step would be to see if it works then load Win XP from scratch if it doesn't. (Or load Win XP anyway...we'll see.) All drives are visible to fdisk and hdparm. I am able to mount /dev/hdi as my kernel does support VFAT but I cannot mount /dev/hdk as I do not have NTFS support built for this kernel, nor do I want to add it. godzilla ~ # hdparm -tT /dev/hda /dev/hda: Timing cached reads: 1108 MB in 2.00 seconds = 552.70 MB/sec Timing buffered disk reads: 86 MB in 3.06 seconds = 28.12 MB/sec godzilla ~ # godzilla ~ # hdparm -tT /dev/hdi /dev/hdi: Timing cached reads: 1120 MB in 2.00 seconds = 558.69 MB/sec Timing buffered disk reads: 138 MB in 3.02 seconds = 45.66 MB/sec godzilla ~ # godzilla ~ # hdparm -tT /dev/hdk /dev/hdk: Timing cached reads: 1100 MB in 2.01 seconds = 547.35 MB/sec Timing buffered disk reads: 138 MB in 3.02 seconds = 45.72 MB/sec godzilla ~ # godzilla ~ # fdisk -l /dev/hda Disk /dev/hda: 30.7 GB, 30735581184 bytes 16 heads, 63 sectors/track, 59554 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 203 102280+ 83 Linux /dev/hda2 16878 5954321503002+ f W95 Ext'd (LBA) /dev/hda3 2043251 1536192 82 Linux swap / Solaris /dev/hda43252 16877 6867504 83 Linux /dev/hda5 16878 4532614337855 83 Linux /dev/hda6 45327 59543 7165084+ 83 Linux Partition table entries are not in disk order godzilla ~ # godzilla ~ # fdisk -l /dev/hdi Disk /dev/hdi: 82.3 GB, 82348277760 bytes 255 heads, 63 sectors/track, 10011 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdi1 1637451199123+ c W95 FAT32 (LBA) /dev/hdi26375 1001129214202+ f W95 Ext'd (LBA) /dev/hdi56375 1001129214171b W95 FAT32 godzilla ~ # godzilla ~ # fdisk -l /dev/hdk Disk /dev/hdk: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdk1 * 1191215358108+ 7 HPFS/NTFS /dev/hdk21913446220482875 17 Hidden HPFS/NTFS godzilla ~ # Now, I wanted to try booting the Win XP drive but I hit a road block.

[SNIP A LOT OF STUFF] If not I could reconfigure the internal cables to share the new drive, at least the Win XP drive, on the chipset cables, but I'd prefer not to do that it possible. Thanks in advance for your ideas. Cheers, Mark Mark, I did what you want to do a few days ago and the system works fine. My steps where as follows: 1) Want Linux disk as hda, Windows as hdb 2) I had the windows disk already installed, like you, needed to install the linux setup. 3) Being totally paranoid about my ability to get the drive designations correct, I totally removed the Windows disk and then did the Linux install. Loaded Grub into the MBR on the hda. 3a) If I had had two empty disks and wanted one linux, one Windows, I would only place one disk in the machine at a time, do the appropriate OS install, boot it, make sure it was working before doing anything else. 4) We now have two disks and two OS's. Linux is on hda, Windows on hdb, both of which have their own bootloaders and can boot in their own right. I followed the Grub install process as outlined in the Gentoo install manual, setting up the Grub.conf file as outlined in Chpt 10, listing 3. I tried to reboot, and Linux came up. I then tried to reboot into windows and nothing happened. 5) Googling revealed that you need to make Windows think it is on hda when it is actually on hdb. I added the two lines, as suggested by Alex: map (hd0) (hd1) map (hd1) (hd0) to grub.conf so it became: title=Windows XP map (hd0) (hd1) map (hd1) (hd0) rootnoverify (hd1,1) makeactive chainloader +1 saved, rebooted, selected Windows and it started up. Once you know what to do, it's quite easy, it's the finding out what to do in the first place that is the problem ;) Some people mention problems about sharing or overwriting MBR's etc, don;t worry about it, just set everything up so that they can individually boot then let Grub handle everything. Any problems, bounce me an email Regards, Andrew p.s. I'm not sure on the partition on the rootnoverify - read up on that -- gentoo-user@gentoo.org mailing list

It won't overwrite the drive, just the part of the MBR containing the bootloader code. You'll just need to run grub from a live CD and do root (hd0,X) setup (hd0) to restore it. -- Neil Bothwick Hi Neil, I'm attempting the new install of Windows but it won't go. I hope I'm just missing something easy. Thanks in advance. My system: Drive 0: Gentoo - partition 0 is boot. 100MB - 30GB - grub is on this partition - The drive has no space left - All the audio for this box is 400GB of external 1394 drives. Drive 1: For WinNT - 80GB - completely empty Drive 2: Audio Data - 80GB - GigaStudio audio sampler data files I've told Win XP to put the C: partition on drive 1. It then gives me the message: ** To install Windows XP on the partition you have selected, Setup must write some start up files to the following disk: 29312 MB Disk 0 at ID 0 on Bus 0 on atapi [MBR] However this disk does not contain a Windows compatible partition. To continue installing Windows XP, return to the partition selection screen and create a Windows compatible partition on the disk above. If there is no space available, delete and existing partition, and then create a new one. To return to the partition selection screen press enter. ** Even though it says [MBR] above it won't proceed without creating at least one partition on drive 0. It appears I cannot install Windows XP on a second drive without writing 30MB to the boot drive? Is it possible to safely shrink an ext3 partition on the current drive 0 to make way for this? The only other thought that comes to mind at this point, assuming I haven't missed something obvious, is to rearrange the drives in the box and make drive 1 into drive 0. If I then installed grub on the Windows drive and fixed up fstab and the contents of grub.conf to recognize Gentoo on drive 1, would it work? Thanks, Mark -- gentoo-user@gentoo.org mailing list
