Has anyone managed to install uport 386 3.0e onto a Zenith Turbosport and could give me some help. Zenith Turbosport: The Turbosport is a luggable 386 machine with integral hard disk and 1.44Mb 3.5" floppy. In way of expansion it has a serial and parallel port and and a proprietary (?) system expansion port which is intended to link to a Zenith 3 card XT expansion box. Notes: 1 - It has no port for attaching a secondary drive. 2 - The 3.5" drive parameters cannot be altered using the machine's own SETUP utilities. (As far as I can see). 3 - It will run Xenix and Interactive UNIX (so the adverts and Zenith engineers say). Attempts so far: Using MSDOS: 1 - copied (1.2Mb 5.25") boot disk sector for sector onto 1.44Mb 3.5" - failed. 2 - copied boot disk first track to 3.5 first track and then did a sector to sector copy of all the remaining sectors starting at the second track - failed. When tried to boot off the disk got "Diskette unit 0 must be quad density". This message comes from the boot disk's first sector - a hex edit proved this. 3 - Did the same as 2 but edited the boot sector so that the 3.5" was labelled correctly as a 18 sector per track 1.44Mb disk and not a 15 sector a track 1.2Mb disk. This failed with the same error as above. Using 286 uport (286 with both 1.2Mb 5.25" and 1.44Mb 3.5" drives): 3 - Formatted 3.5" disk to 1.2Mb (15 sectors a track) (Under DOS). Used dd to copy boot disk onto this 3.5" disk (sector for sector). Failed with "Diskette unit 0 must be quad density". (mknod for second drive set as a 1.2Mb drive with 15 sectors a track). Next I will try to: a) Create character and block special files using mknod for a 1.44Mb 18 sectors per track secondary floppy device. b) and build a boot disk onto a 1.44Mb disk in this drive either by copying (and manipulating the data from) the 5.25" uport 386 3.0e boot disk or by building from the 286 uport installed on the 286 machine (I know that the 286 version works). Questions: 1 - Is it possible to copy a boot disk (onto a different media) using MSDOS perhaps with a little bit of hex editing! 2 - What does the "Diskette unit 0 ...." error message mean? I thought that the boot disk would have to be at least 1.2Mb capacity which, I believe, is high density. 3 - Does anyone know the mknod settings for uport 286 for a 1.44 disk drive? (A second drive).

This message comes from the boot disk's first sector - a hex edit I did some consulting work after I left Microport. One of the things I did was to make an installable system from 3.5" floppies. That message you got was from the boot code. It pokes around in the bios to see what kind of drive you've got installed. You may be able to get a new 3.5" boot from Microport and then copy all of your run time disks onto 3.5" floppies. using something like cpout. -- Ken
