testing DR-DOS for incompatibility ..

support in the wina20.386

Other areas I know DR-DOS is weak:

* Their disk cache sucks

* They probably have problems with some rational extended programs such as lotus release 3.1 when they're loaded in the HMA.

Should test them with QEMM (their has been talk on their forum that QEMM doesn't support them).

I added philba, tomle, and mikedr to cc line. They may have some good input.

DOS Marketing would like to have a second round of dr dos testing done. After speaking with Terri, she mentioned to me that XCAL tested dos 5 in a networking environment with dos and windows apps.

I would like to have a similar test done with dr dos 5. This way we can see how dr dos and dos 5 compare under the same environment.

While XCAl did an extensive study of dos 5 using a variety of apps, I think we might want to take a subset of those apps for dr dos. This would keep the costs down but still compare apples to apples.

Here is where I need your help. I want to come up with a list of those appls that we think are best suited to test with dri. I want dri tested with networking software, a memory manager, dos and win apps and anything else you can think of that might raise some degree of incompatibility.

FIY, our Windows PSS people are receiving calls reporting problems with dr dos and win 3.

In order to tell a strong story we need to explore where dr dos is vulnerable.

Working on a 286 and 386 CPU version. None specific how they will deliver, as one or 3 different SKUs. Hints that th new version will fine tune their memory management, add Data security and better utilise the HD storage capacity. (unsure if this means compression or less gaps) He is convinced to get a next verson out this summer. He hints that the public should look forward and judge themselves of this could be jsut a new version or a new generation. Brad what do we know about this?

DRI is agressing big time, in our accounts. This past week marks more activity that we have seen from them than ever before we have seen this press release, run into them at a start up down in LA and in Swan computer an account we do value (FG DOS goig to royalty DOS) Brad i do not know where the 250k units came from, we have not data to suggest. Entertainment marketing is that big, they are the guys who sell inexoensive things on the cable shopping nework. (YES we HATE losing them.) If we know about the fact we are in competition we will employ you Kathleen do we need help on Swan ?

We will redouble our efforts to compat these guys. I have a few ideas myself.

i'm confused. did dr get a win with this premier company for 250K units a year or is the other mail trying to imply otherwise, could you clarify this for me?

If yes, i'm sure yu are as angry about this as i am. we may not get every win, but i would really like to know ahead of time when an account is close to dr, and it appears that in this case we may have had no idea if dr is getting close
