ISO boot from FAT/NTFS/USB (GRUB.exe, grldr from boot.ini)

Hello,

I am hoping this may be a clue. I found that from a knoppix V6.2.1. booted PC I could not access my NFS shares but I could from the same PC but booted from my knoppix V5.3.1. build. I would get a

Code:

mount.nfs: operation not permitted

After some googling I found I needed to add "ver=3" to my script:

Code:

mount.nfs 192.168.xxx.xxx:/nfsroot /nfs1 -o 'vers=3' -o nolock

If the files generated by the knoppix Terminal services & thus ruymbeke files as well, use the same approach then this would explain my problem. Although what the resolution is remains, got to identify a problem first to fix it. Either I need to look at the configuration of my nfs share or minirt.gz requires modification.

Ruymbeke would you be prepared and do you have time to give some thought to this?
Any help would be much appreciated ( or I should say any further help would be much appreciated ).

Regards,

Will

Hello,

Here is a quick update.

Built a new debian server based on 504-i386 to replace the sme server and now I can PXE from a nfs share.

In line with V5.3.1 I could not PXE my laptop which has a Broadcom 4401 nic, using b44.ko.
By strace insmod b44.ko & trial and error I found that adding ssb.ko and pcmcia.ko to /modules in the expanded minirt.gz file ( and re-compressing of course etc) fixed it.
It appears b44.ko is dependent on ssb.ko, which in turn is dependent on pcmcia.ko. Although the pcmcia.ko surprised me it is definitly working and I have now used the technique to pxe from V5.3.1. as well.

Could anyone perhaps help with a better dependency check than the one I have used?

ruymbeke, if you agree with my findings would you be prepared to add them to your customised minirt.gz files? Plus, I have the bigmem version working as well now, so a BIG thankyou to ruymbeke.

Finally, I now find that machines using a bnx2.ko freeze on v6.2.1. Again they work fine on V5.3.1 and again this is on PXE only. From cd both versions work fine. I have the firmware files in my build. How does this work if there are no firmware files in the minirt.gz? Does anyone have any ideas on this?
It locks up here:

Code:

Probing network device(s) handled by bnx2.ko

I tried adding a intel nic adapter & pxe'd from that but it still locked up at the bnx2.ko stage. The broadcom is on board & cannot be disabled.

Regards,

Will

The forums have changed. Links are broken now. Gilles, your VMWare links that point here are running into a "not found" error here, as well as, the links you have managed at the first post of this thread.

What genius decided to improve the forums?
What a Great Improvement!

Well, I decided to toy around with VMware, and since I could not find the vmware tools for linux guests, I thought I'd look over at VMware.com for one of your Virtual appliances featuring Knoppix 5.3.1.

Well I do have one working... but without the tools for linux guests.... it sucks.
Gilles... I am running vmware player 3.1 on XP host. Do you know where I can get the tools for linux? Even downloaded Workstation and it didn't seem to have any iso's in it... just a 300+ MB script... that after I ran, didn't have any iso's in /var Or your knoppix 5.3.1 appliance would be great too.

Best,
johnrw
