My System configuration is as:
IDE Hrad Disk = 80GB
RAM = 512MB
While doing installation of SCO Open Server 5.0.7, I got stuck at second phase (i.e. IQM). During this phase, I selected for "Fresh" installtion and after that go for "Customizing Partitions and FileSystems". But it automatically takes "Total available space on disk = 159MB". Of 159MB, it alocates 64 MB to root(/). Now Optional Software size goes beyond the size of root . So, I now I have two options:
1) I can increase the size of root , or
2) I can reduce the size of "Optional Software Selection"
As i cannot increase the size of root because it shows "Total available space on disk = 159 MB", which is unalterable. Initially, it takes 320MB for "Optional Software", which is 256 MB greater than root. Now I reduced the size of "Optional Software" to 54 MB by deselecting all the softwres which are initially selected.
But as i proceed further, it displays an error saying -
"There are not enough disk resources"
for root(/) filesystem, space needed = 127MB
Check to see if the unix partition is using the whole disk in fdisk (multpile partions on the HD).
Check to see if the disk params are such that fdisk sees the entire disk(disk geometry is not correct).
The capacity of the disk drive is equal to the number of cylinders times the number of heads times the number of sectors per track times 512 bytes per sector.
If any of these values are not correct in the CMOS, or the value of one of these parameters overflows the field size allocated by CMOS then the size of the disk will be reduced accordingly.
If the hard drive has been used before, there may be other partitions still on it for those operating systems, leaving only 159mb for Unix, or there may have been a 159mb Unix partition on the drive.
If you choose the most manual installation, then you can run dparam, fdisk, and divvy.
dparam will allow you to enter the cyl,heads,sectors and stores them in the master boot sector.
fdisk will allow you to remove other partitions and create a new partition.
divvy will allow you to divide the partition into file systems.
