LBAcache / STAK nest error
I'm having a problem with UBCD running off an USB stick. It works fine on all the Desktops around, but on both the IBM/Lenovo T61 and X61 series the freedos disk fails in an interesting way. It displays funny messages like
"LBACACHE: in. STAK nest!? otherss=00d3"
whenever it tries to access C: (i.e. the USB drive).
As far as I can tell, this is a problem with LBACACHE, because if I use the "Clean Boot" entry I can access the USB stick (as C:) just fine.
Unfortunately even the "Ultra-Defensive" boot option doesn't have an option to skip LBACACHE, so I'm a bit lost on how to fix/workaround this problem.
Can anyone help?

Re: LBAcache / STAK nest error
OK. I managed to work around this problem.
Fixed ubcd/images/fdubcd.img.gz by
- gunzip the file
- loopback mount the floppy on linux
- delete BIN/lbacache.cab
- unmount
- re-gzip
- replace fsubcd.img.gz with the new version
The such patched ubcd now works fine on the formerly problematic laptops.
Having an option to disable lbacache in the next version would be a great idea.

Re: LBAcache / STAK nest error
I can't find a way to make lbacache selectable on bootup like cdrom or lfn, but I can make the ultra-defensive option launch without lbacache.
The problem is lbacache is located in bin, for which menus are not supported.

Re: LBAcache / STAK nest error
Is there a way to use detect a nolbacache parameter specified on the MEMDISK command line, whit mdiskchk.com, at that stage?

Re: LBAcache / STAK nest error
Conceivably, since menu interaction is not involved, and mdiskchk.com is already available at that stage.
So what do you have in mind? For users to update the menus and add "nolbacache" to every "memdisk fdubcd" line? Might be more convenient to introduce a single flag in "/etc/global.set" on fdubcd.img instead.

Re: LBAcache / STAK nest error
Because it only fails on a very few models, I think a "nolbacache" MEMDISK parameter would be better. Or, if possible, let the "nolbacache" MEMDISK parameter, change the "/etc/global.set" file, from:
to:
So you can provide the "nolbacache" MEMDISK parameter or you can change the "/etc/global.set" file.
Code: Select all
nolbacache=0
Code: Select all
nolbacache=1
