Hi there! I've got a Seagate ST4096 drive that needs to be installed in an IBM AT. I am looking for some info regarding its drive type so that I can partition and format it without using a third party's partitioning software. Is this even possible? The reason being that this AT will be running Microsoft Windows 2.11 most of the time and it would be nice to be able to use their disk caching driver Smartdrv.sys (which causes problems with partioning software such as SpeedStor). ANY help and/or pointers will be appreciated. BTW, the exact setup of the AT is as follows: 512K on the motherboard (8 mhz) 2048 expanded memory vi an Above Board ATI VIP VGA card Microsoft Mouse Thanks in advance !!

The st4096 has 9 heads, 1024 cyl., and a standard formatted capacity of 80 meg. The closest you can come to that setup on an old style AT with 14 drive types is type 8 which means you will loose disk space. On the IBM CMOS setup chart for drives on the IBM will not handle the drive. Some of the other BIOS's may handle it directly. I have an st4096 in my AT and am using Disk Manager and have had no problems with any of the other software that I want to run. It will not run under OS/2 though. -- Let sleeping dragons lie........ | The Bit Chaser ---------------------------------------------------------------- Bill Wilson (Bitnet: ucc2wew@nauvm | wilson@nauvax) Northern AZ Univ Flagstaff, AZ 86011
