I acquired enough parts cheaply enough to put together some Warp 3 boxes that may be saleable as a means of promoting OS/2. Star Office wil be installed as the main app. These will be 486s on VLB mainboards with a combo VLB video cum I/O card. The video chip is a Cirrus Logic 5426. The uarts are only 8250s so one for a modem will go through a supplemental serial card with a 16550 uart. The VLB achieves reasonable video acceleration so the screen performance looks acceptable to me. I have applied FP39 to the base operating system (and left MMOS2 at FP26 for the present) but as noted before I couldn't get the ESS1868 to work beyond FP26. I can't leave it at FP26 because the latest Netscape 2.02 requires FP35 or above I think. When the ES1868DD.sys device driver loads it crashes with a Trap D and the following (excluding the register information - please tell me if these are required): location 0168:fff49162 - 000e:c162 6000 9084 048600b4 Internal revision 8.263_uni, 98/10/14 From previous communications in this group I got various versions of the ESS1868 driver all with the same result, except that I didn't note the location and other details each time. Trying to use a sound card with a different chip led nowhere! The Avance Logic System's ALS120 chip gives no sound at all. Same with an Aztech 1605 or something like that. The device drivers appear to load correctly as config.sys is processed but no sound. The device driver packages were downloaded from ALS's and Aztech's sites as something like ALS100+_W3.zip and Nova-OS2.zip, unzipped and installed using MInstall. I commented out the lines invoking the ESS driver. The other config.sys lines relating to D:\MMOS2 were left alone. The ALS card works OK under Windows 3.11, didn't try with the Aztech. Wondering if any of you can help me get through this bog? I know my Creative Sound Blaster card works (at FP39) but I don't want to have to fit one of these since even now they are too expensive. My idea is to produce a *low cost* Warp 3 box to maximise the chance of getting new OS/2 users!
