- Did you delete your config.sys file in the root of the OS/2 drive ?
- If not, you might have migrated the 'SET DELDIR=...' lines of the old
- config.sys. In the 2.1 beta, this will lead to a TRAP D (it did at least
- for a few people) as soon as a file is deleted. DSPINSTALL did the same
- with my system, when I installed it over GA+SP. Previous installation on
- its own *empty* partition worked fine, since by default the 'SET DELDIR...'
- lines are REMed out in config.sys and autoexec.bat.

-
- Yes. You have to UNPACK the DSPRES.DLL file (I assume the TRAP D happened
- immediately after DSPRES.DLL was copied, being the first file) from the
- Display Driver disk yourself 'UNPACK a:\dspres.dl_'. To run UNPACK, boot
- from a floppy (or the installation disks, if you don't have a bootable
- floppy ->> read the FAQ from here on if you don't know how), run CHKDSK and
- then UNPACK. You might have to replace more than DSPRES.DLL, if the
- DSPINSTALL did delete more files (which I doubt). The Display Driver disks
- contain *.dsp files, which list the necessary drivers for each card. The
- name of the *.dsp file is a combination of the card type (TS for TSENG) and
- the resolution.
-
- >b) What is Trap 000d and what does it mean in this case?
-
- TRAP D is a General Protection Fault having an invalid pointer as its
- most common cause. In this case it is a bug in the DELDIR mechanism,
- I suppose.
-
- >c) Has anyone else installed 2.1 Beta with Paradise Video?
-
- For me, it runs fine now in 800x600x256 with TSENG ET4000.
-
- >d) Is there a way to correct Cross Linking in EAs?
-
- As far as I know, CHKDSK X: /F:2 , where X: is your drive is the only
- way to correct it. But it might have been a good idea to run CHKDSK
- *before* you install the new system.
