    DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 15 T BIOS H ARDDISK IMITATIONS Note: The ELAN400 with the SYSTEMSOFT- BIOS does support maximum 8192 cylinders (ca 3GB !) by Jan Steunebrink Version 2, June 1999 This article is published at <http://web.inter.nl.net/hcc/J.Steunebrink/bioslim.htm> Contents •...
  • Page 171 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 The 504 MB BIOS Limit The (in)famous 504 MB (528 million bytes) limit comes from the fact that the ATA (IDE) specification has different limits than the BIOS. When the traditional BIOS Int 13h interface is used to control an (E)IDE harddisk, the limits are combined as illustrated below.
  • Page 172 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 Example: A 2014MB drive has a CHS count of 4092x16x63. According to the above method, this will be translated into 1023x64x63, nicely within the Int 13h interface limit. In other words; DOS (or any other OS which uses the BIOS Int 13h interface for that mat- ter) thinks that it deals with a drive which has 1023 Cylinders, 64 Heads and 63 Sec- tors/track while the BIOS still controls the drive with its original geometry.
  • Page 173 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 Does my BIOS support translation? Now that the theory has been dealt with, it is time to answer this question. First check your BIOS date. If it is 7/94 or later, chances are pretty good that you have a translating BIOS.
  • Page 174 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 This trick assumes a PC with one < 504 MB harddisk and a BIOS with user definable drive types. • Enter the BIOS setup and select for the second (non-present) drive a CHS of 2048x16x63.
  • Page 175 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 • When a cylinder count of over 4095 is entered in the BIOS setup, the BIOS will cause a system lock-up at boot time, making the entire system inaccessible.
  • Page 176 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 Apart from the last scenario, I don’t know any other reliable method to detect this 2 GB limit than by hooking up a drive with more then 4095 cylinders. However, you may have found something when using “the trick” for detecting a translating BIOS. (See above) BIOSes dated May 1996 or later should be free of these problems and support translation up to the Int 13h interface limit of 8 GB.
  • Page 177 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 The Int 13h extensions - Breaking the 8 GB barrier With the rate in which the harddisk technology is progressing, we are now faced with EIDE drives exceeding the 8064 MB limit of the Int 13h interface.
  • Page 178 DIGITAL-LOGIC AG MSM486SV/SN Manual V2.5 Last but not least, we need a partition utility capable of creating partitions above the 8 GB boundary which the OS can see. The version of FDISK supplied with these Operating Sys- tems is able to do this with the aid of new partition types 0Eh and 0Fh (FAT16) or 0Bh and 0Ch (FAT32;...
