|How to upgrade:|
|1||Download one of the BIOS files below and rename it Z64BIOS.IMG|
Use this file on a ZIP disk to update your Z64 BIOS
|ATTENTION -use the LCD panel- keep your N64 turned off during the BIOS update procedure - better remove the Z from the N64 before BIOS update.|
|After this BIOS update your Z should continue to work with the ZIP drive as before. |
|What if the flash-upgrade fails? You risk to lose all disk-access.|
This is a dramatic case, but the Z is not completely lost.
The rescue page may help you to bring it back to normal
|2|| Turn the Z64 off, open it and install the new drive.|
-- Harddisk partitions must be FAT16 and formatted --
For small harddisks, attach the Z HD as single HD to a PC and use a DOS5 boot-disk to partition and format.
For harddisks bigger 8.4Gig, the Z64 can "only" access the first 8Gig of the drive, and the disk should be partitioned according this picture:
-- For ORB disks use the ORB-Tools to partition & format --

These BIOS files are experimental work and were tested for basic functionality only.
The modification to the original BIOS release from Mr.Backup is in the startup files. The game-play and backup is still the standard ZBios with the same version number.
|rom217zd.img - Z64flash-bios file 2.17 for ZIP, HD and ORB drives|
|Tested with a 2.2Gig ORB-Disk, 4.8Gig 2.5' IBM DADA24860, 2Gig SeagateST32140A,
20Gig IBM-DJNA-352030, ZIP250 Drive and inbuilt ZIP100|
Contains the OnSpec HD driver supplied with the ORB-tools and system files from DR-DOS 7.03.
Connect the ZIP as slave when using HD and ZIP together. In this case, the Z must be off for disk change.
ORB and ZIP can't be connected the same time.
The Z displays up to 6 disk partitions as folders DISK-2 to Disk-6 (or 5 and the ZIP).
If the first drive (root) contains a file "Z64START.BAT", this file is processed as DOS batch file at power on. (Sample)

|Version 2.18 of the Z-BIOS is not from MR. Backup. It was released to the internet in July 2000 and seems to be fully functional. We should encourage the developer to continue with enhancements for the Z64. One major problem is still the proper backup & restore of the flash save-memory.|
