I want to change the order the system looks for the valid system disk from A:, B:, C:... to C:, A:, B:... so that either the hard drive is check first, or that the disk drives are not checked. I would prefer to just change the order, not knock out the diskette drives. Thank You. Chris Behrens ChrisB@Hubcap.Clemson.Edu

I would prefer to >>just change the order, not knock out the diskette drives. The order in which the system checks for a boot disk is A: then C:. B: is never checked as a boot drive (execpt on one card I remember reading about). Neither is D:, E:, etc. checked. The only bootable drives are A: and C:. At startup, the computer verifies that drive B: is present, but it never tries to boot from it. The only way to have the computer try booting from drive C: first is to have no A: drive in the machine (ie. disconnect the drive cable or disable the drive in setup). But you said you would rather not sacrifice a floppy. However, if you simply tell setup that there is no drive A: you can always easily reenable it when you need it (just a suggestion for machines with setup in ROM). Unfortunately there is no way to change the order in which the computer checks its boot drives.

Also has an option to prompt the user for a boot disk before atually booting up the system. I am using a Microid Research BIOS (version 1.1).

The laptop computer from GRID (Gridcase 1530) always boots from C: unless you hold down a certain key during the boot time. The machine came with its DOS installed and the manual says nothing about how it is done. Anybody has any idea how they do it ? ========================================================================== N075BE@TAMUTS.tamu.edu Heon Yeom ==========================================================================

Regarding the subject of selecting boot devices and partitions, I have to gloat a little bit. **All** Tandon systems offer this feature. We optionally provide a boot menu listing all partitions (active or not) on up to 4 boot devices. This can total 16 different items to boot from (which I have only actually seen once!) It requires smart BIOS **and** an operating system that does not assume it is the first device on the disk controller (unit '80'). Our systems require Tandon DOS to fully support all these features. EXAMPLE: Unix and Xenix will only boot from the primary device. We have offered this and an integral setup screen in our BIOS since 1986, and we were the first to offer either feature. The setup screen can also be set to run in any of 6 languages... Enough for now... As mentioned in an earlier article, the only other systems **I** have seen that offer a selectable boot order are those containing Microid Research "Mr. BIOS." Understandable. The developer of Mr. BIOS used to work for me! We called him Mr. BIOS in our hallways here... He's going gangbusters and I wish him well.

It first checks A:, then the first hard drive partition. I have three floppies, A:, B:, and C:. My HD starts at D: and it boots fine from there.
