It is belived that John Harris originated * the idea and others added some embellishments. This * particular ramdisk is different from most in that it * can be resized or removed. * * use - The ramdisk can be sized the following three ways: * * a) By a ramdisk spec found in \auto\ramdisk.dat * b) By entering a ramdisk spec through the console * c) By not doing a) or b) to get the default spec * * The ramdisk spec has the form yxxx where y is a drive * letter [a-p] and x is a digit [0-9]. A successfully * created ramdisk will have a number of clusters equal * to the number xxx and be installed on drive y * (note that number of clusters is number of kbytes). * The default ramdisk spec is h100 (100k ramdisk on * drive h). To install a ramdisk you must put eternal2.prg * into an AUTO folder. You may also create and put a * ramdisk.dat file (containing a ramdisk spec) into the AUTO * folder but it is not necessary to do so. To install for * the first time, put the disk with the AUTO folder into * drive A and press reset (or switch on the computer). * A ramdisk will be set up according to the spec in the * .dat file, if it exists, or according to the default spec * unless you press either the "caps lock" or the "alternate" * key during boot. If you press "caps lock" no ramdisk will * be set up (you must keep the key depressed until bootup * is finished or you see that etrnl2.prg has finished * executing). If you press "alternate" you will be prompted * for a ramdisk spec. Enter the spec and hit return to * create the ramdisk. To remove a ramdisk, press reset and * keep a finger on the "caps lock" key. To resize a ramdisk * press reset and keep a finger on the "alternate" key * until you see the prompt. Then type in the spec and hit * carriage return. If a ramdisk is installed, the auto * folder exists on a disk in drive A, reset is pressed and * you keep your fingers off the keys, the ramdisk will still * be present with all its original files after * re-initialization. To prevent a ramdisk from being * created at startup use Q for the ramdisk spec in the * ramdisk.dat file. The ramdisk.dat file must have four * characters otherwise. To get a ramdisk of size less than * 100k on startup use leading zeros in the size field of * the ramdisk.dat spec. * * notes - A ramdisk spec with two or one digit(s) is also legal. * If you use a ramdisk spec like m0 you will get a size zero * ramdisk but you will have lost 9k of space to the overhead * used in setting it up. Therefore, the proper way to * remove a ramdisk is by means of the "caps lock" key. * If you give no ramdisk spec then the default h100 is set * up. If you give only a device letter, say m, then a RD * with spec m100 is set up. There is no button to push to * abort - simply letting the boot process run its course is, * for all practical purposes, an abort. * * John Franco * Bloomington, IN * 1/30/87 ------------------------cut here-------------------------------------- begin 644 etrnl2.prg M8!H```-D````,````@8``````````````````"I/+GP```68*FT`!"`M``S0 MK0`4T*T`'-"\```!`"\`+PT_/```/SP`2DY!W_P````,0J<_/``@3D%*`H6"@H&9@!4:&4@9&5F875L="!R86UD B:7-K('-P96,@:7,@:#$P,"`H,3`P:R!R86UD:7-K(&]N#65F ` end -------------------------cut here---------------------------------
