"It dosnt signify "type 47 or 48 etc"..."

Depending on the BIOS, "47" or "48" may be different numbers. Cycle through them and see if there's any where you can change the parameters (usually the first or last ones in the list).

"it dos'nt seem to save the paramaters when i save & exit/re-start (F10 - F5)"

Sure you're working with a fresh CMOS battery (and correct type)? Is there any possibility something's shorting out that would drain a battery quickly?

"disk 1 202 mb Should be 212mb"

Likely the difference is between the unformatted capacity (212MB) and the formatted capacity (202MB):

You need to enter the BIOS and ensure all settings are correct, especially that it is showing the correct hard drive size!

Googling is quicker than waiting for an answer....

Jolicloud is correct. Old machines (most 486's or older) don't have the ability to auto-detect a drive, so that info (and perhaps more) was lost when the battery died or was swapped-out. You may even need to open the machine back up to get the drive geometry (cylinders, heads, sectors/track, landing zone, etc.) off the drive---or the model/make of it to search for those parameters on the web...

"it wont let me manually enter the values i found on the drives",

Is there something like a "Type 47" or "Type 48" setting available (dependent on the BIOS manufacturer)? These are "user-defined" types, meaning you can input the geometry values manually.

It dosnt signify "type 47 or 48 etc" it just toggles through numbers and depending which number you highlight it comes up with a list of paramaters.
none of the options match exactly with my drive capacities, and it dos'nt seem to save the paramaters when i save & exit/re-start (F10 - F5)
cyl heads sectors precomp landz
disk 1 202 mb Should be 212mb 987 12 35 none 987
disk 2 405 mb should be 425 mb 989 15 56 0 0

Glad we could help. At least my working with "old iron" can still help out someone...
