Hi Bernd, Jack is right, "pipeline" based DVD burning saves a lot of space for temp files. Of course you are also right - you cannot easily put temp files on harddisk if the harddisk only has NTFS etc and it would be asking a bit much to add another harddisk. Well, of course DOS USB (storage) drivers are improving a lot now :-).
I still like the idea to use memory above 4 GB only for easy things such as RAMDISK... Yes, JEMMEX could use big pages or PAE or both to access more RAM for various things, but this always leads to the question: How compatible will it be? At the moment, JEMMEX already is too fancy for many ancient DOS games which use pre-VCPI DOS extenders, so it is good that HIMEMX and JEMM386 are still separately available. If a new driver provides some kind of XMS 4, but only at the cost of dropping, say, EMS 4 or VCPI support, then that XMS 4 mode should be command line switchable at least :-). By the way, I think that you should not map too much stuff over the now unusable last 0.n GB of the first 4 GB. After all, the remaining area can be used for framebuffers, BIOS and MMIO so whenever it is marked as non-accessible, there will usually be a good reason for that. Same as with UMB. Talking of which, I wonder whether JEMM386 can become even more clairvoiant about avoiding unusable UMB, now that modern hardware and BIOS frequently fail to mark such areas right. > 2) Computer has 12GB RAM (hello brand new Core I7 system Hello waste of electricity... > 4) DVD can contain more than 4GB, so the file fits on it. Next task would be to find 4 GB of actually nice DOS software. > 5) No ISO generation necessary as your above mentioned buffer Indeed, although DOS is not exactly strong in pipelines ;-) > 7) No USB sticks around with sufficient capacity and free space Depending on speed, 4 GB USB sticks are 10 - 40 Euro today... For comparison, smallest quad core i7 CPU is already 250 and 6 GB of DDR3 are 130 to 360 Euro at the moment. Same with a much less fancy hardware: 4 GB DDR2 is 40 to 90 Euro and an Athlon64x2 4450E for 40 can also handle 16 GB on nForce630a already... So YES people can have so much RAM (but why? Not even Vista can waste it yet) but NO using RAM is by no means a cost efficient way to have 4 GB of storage in your PC now. > With lack of UDF driver for DOS ("packet writing") I would already be happy with UDF reading. There were even some attempts to make some UDF enabled SHSUCDX afair...? > I know of no other freely usable/distributable DOS optical disk > writing software other than CDRECORD and CDRKIT, both stuck on > ASPI/SCSI...

Or is it just a GUI for CDRECORD? > Maybe soon enough ReactOS (www.reactos.org) will > be a light-enough Windows-replacing environment > and work with your streaming recorder program. ... or Linux ... but yes, DVD UDF is tough for DOS.
