Q1. Adding another disk to a DELL 316SX --------------------------------------- I've a 40 Meg IDE drive on the above and I would like more space - I've been thinking about a large external SCSI drive (theres no room internally) using a 'host adapter' type of interface to the AT bus. Has anyone else done something like this and does MINIX work OK with this sort of setup? People trying to sell me such things assure me this adapter will make the 2nd drive look just like a 2nd AT type drive. I've had a quick look at the AT MINIX driver and it appears to only talk to I/O ports in the range 0x1f0 to 0x1f7. In the Phoenix System BIOS book (ISBN 0-201-51806-6) pages 80-81 these ports are documented as being for disk 0 only, there being a mirror image set for disk 1 at I/O addresses 0x170 to 0x177. Where do you guys that write these drivers get your information? - the Phoenix book although very good would not be enough for such a job. Is the case really that this second set of ports is in fact for talking to a second CONTROLLER rather than a second DISK (I'm certain people are using 2 disks with the MINIX AT driver). Would adding a second disk via this 'host adapter' rather than by hanging a 2nd IDE device on the existing controller require mods to reference this second set of ports? By the way, 1.5.10 seems to work fine on the DELL - 1.3 would sometimes go to sleep with the hard disk light on and would require rebooting but so far this has not happened with 1.5.10 (I don't understand why they didn't put a reset button on the DELL) Q2. Can I scrounge Bruce Evans 16/32bit compiler binaries. ---------------------------------------------------------- I've managed to get hold of Bruce Evans Kernel patches for 32bit mode, together with his bcc and bcclib - can some kind soul send me a copy of the 16bit and 32bit compiler binaries? I did a quick mod to 1.3 to correctly work with a UK Keyboard (before that the game was called "hunt the '\'"). Anybody interested? (I've not got round to it yet for 1.5.10). Thanks in advance Graham.
