It ** defines the number of tracks there are in the disk. Each track con- ** tains 16 512 byte blocks (or 8K of information). Changing HighCyl ** and rebooting will cause a fresh (empty) recoverable ram disk to be ** created. ** ** It is better to run out of space on the recoverable ram disk than ** to run out of memory. That is, don't set HighCyl to make a disk ** larger than your total amount of memory. ** ** Remember, the ASDG Recoverable Ram Disk does full dynamic memory ** management. That is, HighCyl is really just a Maximum size. Setting ** HighCyl to a large number does *NOT* mean you automatically lose a ** lot of memory. ** ** HighCyl MUST BE ODD! ** ** Suggested HighCyl Values: ** ** Fast Ram Installed HighCyl Value Max Ram Disk Size ** ** 0 15 128K ** 512K 31 256K ** 1Mbyte 63-95 512K-768K ** 2Mbytes 127-191 1Mbyte-1.5Mbytes ** 4Mbytes 255-383** 2Mbytes-3Mbytes ** 8Mbytes Anything less** ** than 1024 ** ** REMEMBER: If you have Fast Ram that autoconfigs, some amount of ** it will be used by the operating system even before the recoverable ** ram disk starts up. So, you've actually got about 100K less than ** you think. ** ** NOTE: Using Addbuffers with the ASDG Recoverable Ram Disk will ** slow the ram disk's performance. ** */ /* ** Copyright 1987 By Perry S.
