Has anyone taken a stap at porting minix to on of the portables? I am
thinking of buying a T1100+ or an NEC Multispeed with a hard disk, and minix
would make life very nice indeed...

That's what I did with my T1100+. There are a few problems, however. The first is that the screen display dissapears, when data is being output and the screen is scrolling, every other screenful or so; after another screenful of data or so, the screen display reappears. Other people have had this problem, and so it may have been fixed by now (I don't use Minix much). The other problem is that the kernel/drivers will have to be rebuilt (I think) to take full advantage of 3 1/2" disks (i.e., use all of the available disk space); unless this is done, the 3 1/2" disks will only have a usuable capacity of 360K. Hmmm. As a matter of fact, I'm not sure how you'd make new Minix file systems on a 3 1/2" disk. MSDOS has to be used to format the disks but, if MINIX doesn't recognize the 3 1/2" disk size (without rebuilding the kernel/drivers), I'm not sure how one would make new file systems. -- Darryl Okahata {hplabs!hpccc!, hpfcla!} hpsrla!darrylo CompuServe: 75206,3074 Disclaimer: the above is the author's personal opinion and is not the opinion or policy of his employer or of the little green men that have been following him all day.

That's what I did with my > T1100+. Thats what I did for my Datavue Spark portable. Wasn't too hard (even though the only way I could access 5.25 disks to transfer was via serial port on an IBM AT). > The other problem is that the > kernel/drivers will have to be rebuilt (I think) to take full advantage of > 3 1/2" disks (i.e., use all of the available disk space); unless this is > done, the 3 1/2" disks will only have a usuable capacity of 360K. Hmmm. Not a solution (more like a hack) but since I have the latest Minix (1.2?) then can't I make a new file system by referencing your 3.5 drives as IBM AT 1.2Meg drives? (I don't have any docs with me now, but I think you reference AT drives as AT0 and AT1.) So... mkfs \dev\at1 720 will make a file system on a 720k disk. Is this reliable or dangerous? I am new to Minix, as you can well see ;) Then again, I was having disk driver problems when I was using 360k and they haven't gone away with 720k file systems... It seems my system fails test10 ('can't create file' errors) and every once in a while Minix locks up and goes away when I try to write to a disk. Other times, Minix and my drives just purr along. Hmmmm. Could this possible suggest that my Datavue Spark disk system is not quite IBM compatible??? _____________________________________________________________ | maroC ddoT | Todd Coram | | tcoram@udcvax.bitnet | tentib.xavcdu@maroct | | remmargorP | Programmer | | retneC retupmoC cimedacA CDU | UDC Academic Computer Center | |_____________________________________________________________| "Trust me, I know what I'm doing..."
