All the autodetect hard drive does is reads the drives' CHS and other info that goes into the entry area for hard drives. This does not addect the settings for the primary, secondary, master, slave. I believe this is the area he was speaking of. And auto in that area is not always the best setting. > Ahem, Linux ignores the BIOS. Not exactly. The BIOS is used for the boot process, but once the kernel is loaded the BIOS is no longer used. Basically Linux does ignore the BIOS, but it still can cause boot problems. Linux itself does it's own probing for hardware. Much the same as NT does. It is during this probing process where problems with hardware can accur. (As well as the BIOS used when booting the system.) Here is an interesting note: When I am in DOS and boot to Linux from DOS, if I have the sound blaster mic not muted, it will not be muted in Linux. this is because you are warm booting. In WINDOZE, I have it muted in the volume control panel. Another thing you have to careful of when warm booting into another OS is to be sure and flush your HD cache if it is set to delayed writes. Some caches will detect a three fingure salute, but probably will not detect warm booting into another OS. Smart Drive may be an exception to this when warm booting from DOS to WINDOZE and WINDOZE does shut down before entering DOS mode. > > >At present, here in California, it is hard to find an AT board > > First now? It's been impossible for over a year and a half here - if not more. There are several AT boards still available. They are getting a little harder to find, but they are out there. You can also look in the used market for them. Also look for what they call BAT boards. These will work in AT or ATX cases and have both power connectors. > IMHO: > New boards are coming out with 133MHZ Bus (Intel) and now moving to 200 and > 266 MHZ Bus (AMD), with UDMA66 (Intel) and UDMA100 (AMD) as the slowest IDE > controller speed. Yes they are, but who needs this for a DOS box. Why not just find some older technology real cheap. > BTW: I've never even heard of a 166MHz bus. I don't know if this is a standard or not, but some motherboards may have this capability. I have never heard of 112Mhz and 124MHz FSB, but I have seen questions about these speeds, which probably means that someone played with various jumper settings and found them to be available. Since 166 is double 83, it would not seem unreasonable. > > Also, > >almost all of the new boards for the last three years have 2 EIDE > >connectors and 1 SCSI connector (capable of connecting 16 devices). > > SCSI on the motherboard? That's very rare here. I remember seeing some > before IDE-2/EIDE (take your pick on what to call it) was common, but that > was on 486s. This has become very common. These boards use the 80 pin SCSI connectors. They have been around for quite awhile. I think I have seen some with SCSI RAID controllers on them.
