Vampire V4 and V4+ troubleshooting: boot problems, CF cards, peripherals, graphics issues and failed firmware updates.<\/figcaption><\/figure>\n<\/div>\n\n\n

Black screen? Stubborn CF card? A \u201cquick\u201d core update that turned into an evening of regret? Your Vampire is supposed to bring the Amiga experience back to life\u2014not drain yours.<\/p>\n\n\n\n

This AlterEgo guide tackles boot failures, storage headaches, misbehaving peripherals, game glitches and firmware recovery, starting with the checks that leave your data alone. Find your symptom, follow the relevant section and change one thing at a time. Less random tinkering, fewer opportunities to make things worse, and hopefully more time playing games.<\/strong> \ud83d\udcbe\ud83d\udd79\ufe0f<\/p>\n\n\n

\ud83e\udddb Vampire V4 and V4+: The Survival Guide<\/h1>\n

A black screen, an unreadable CF card or a failed core update can have very different causes. Start with the symptom, make one change at a time, and check the result before moving on.<\/p>\n

This guide covers the Vampire V4 and V4+ Standalone only<\/strong>. It distinguishes the standard machine from systems fitted with an Ultimate Expansion Board, and separates ApolloOS<\/strong> instructions from AmigaOS 3.x<\/strong> instructions. Use the hardware, firmware and OS instructions for your exact Standalone configuration.<\/p>\n

\ud83d\udee1\ufe0f Before you start:<\/strong> Keep the original CF unchanged and use a spare for experiments. Writing a disk image replaces the destination's contents. Formatting, partition changes and firmware flashing are separate operations, each with different consequences.<\/p><\/blockquote>\n<\/span>\n

\ud83e\udde9 Keep these five components separate<\/h3>\n
Component<\/th>Purpose<\/th>What to remember<\/th><\/tr><\/thead>
FPGA core<\/strong>, usually supplied as a .jic<\/code><\/td>Implements the processor and Amiga-compatible hardware in the FPGA.<\/td>A core update does not reinstall the CF. It can also change the default ROM supplied with the core.<\/td><\/tr>
Kickstart \/ ROM<\/strong><\/td>Provides the system components needed to start the OS.<\/td>A ROM is not a complete desktop installation.<\/td><\/tr>
Disk image<\/strong>, often .img<\/code> or .hdf<\/code><\/td>Contains disk or partition data.<\/td>The extension alone does not tell you whether it is a whole disk or one partition.<\/td><\/tr>
Operating system<\/strong><\/td>Provides the installed desktop and software environment.<\/td>ApolloOS is based on AROS; AmigaOS uses a different installation and driver arrangement.<\/td><\/tr>
Drivers, utilities and startup files<\/strong><\/td>Connect the OS to the hardware and configure booting.<\/td>These must suit both the OS and core. Downgrading the core does not roll them back.<\/td><\/tr><\/tbody><\/table><\/div>\n

SAGA<\/strong> is the graphics\/chipset implementation. Native<\/strong> screens are the Amiga display modes used by many games and boot screens. RTG<\/strong> provides graphics-card-style desktop modes; the AmigaOS setup uses P96\/Picasso96 and the SAGA RTG driver. ApolloOS does not use that same AmigaOS driver installation.<\/p>\n<\/span>\n

ApolloOS<\/td>Open the desktop's Shell\/CLI<\/strong> launcher. If its menu has Execute Command<\/strong>, enter NewShell<\/code>.<\/td>The Amiga-style commands explicitly marked for ApolloOS or both systems.<\/td><\/tr><\/tbody><\/table><\/div>\n

Run commands one at a time unless a numbered step specifically supplies a complete block. Replace example paths and device names before running them. Quotes around a path keep spaces within that path. A command's error is a reason to stop that procedure and resolve the error.<\/p>\n

On the V4, SYS:<\/code> is the current boot volume; S:<\/code> holds startup scripts, C:<\/code> commands and DEVS:<\/code> drivers\/configuration. RAM:<\/code> is temporary and disappears when power is removed. A backup in RAM:<\/code> is not a recovery copy.<\/p>\n<\/span>\n

\ud83d\udcdd Record the configuration before changing it<\/h3>\n
  1. Photograph the enclosure label. Record the model, installed RAM and expansion board from the purchase details or board markings. Remove power before opening an enclosure to read markings.<\/li>
  2. On AmigaOS 3.x<\/strong>, open Workbench \u2192 About<\/strong> and record the Kickstart and Workbench versions. On ApolloOS<\/strong>, record the exact image\/release name you installed and the desktop's About information. A generic AROS version is not the ApolloOS image's release identifier.<\/li>
  3. Open a Shell and run these read-only checks on either OS:<\/li><\/ol>\n
    Version\nAvail\nInfo\nAssign<\/code><\/pre>\n
    1. Photograph or save the results. Avail<\/code> reports the OS memory pools, Info<\/code> reports mounted volumes, and Assign<\/code> shows name mappings. They do not identify every physical hardware detail.<\/li>
    2. Query an installed utility by its actual filename. For example:<\/li><\/ol>\n
      Version C:VControl FULL\nVersion C:ApolloFlash FULL<\/code><\/pre>\n
      1. On an AmigaOS SAGA installation<\/strong>, inspect relevant files individually where they exist:<\/li><\/ol>\n
        Version DEVS:Monitors\/vampiregfx FILE FULL\nVersion DEVS:Networks\/v4net.device FILE FULL<\/code><\/pre>\n
        1. Distinguish a file's version from the currently loaded component. For a device already in use, Version v4net.device FULL<\/code> can query the loaded device; the full-path command with FILE<\/code> inspects the file on disk. A \u201cno version information\u201d or \u201cnot found\u201d result is something to record, not a reason to install a replacement blindly.<\/li>
        2. If VControl is installed, C:VControl CORE<\/code> and C:VControl CPU<\/code> provide useful status. Keep the original JIC filename and flashing log too: core strings can remain stale after JTAG programming. Do not run these names as if they were ApolloControl syntax.<\/li><\/ol>\n
          To save a command's output, redirect it to a new<\/strong> text filename, for example Info >RAM:V4-volumes.txt<\/code>, then copy that file to a mounted transfer card before powering off. Redirection replaces an existing file of the same name.<\/p>\n<\/span>\n
          \ud83d\udcdd Back up, edit and restore a startup file<\/h3>\n
          Do this on the spare CF<\/strong> whenever possible. These file commands work in AmigaOS and ApolloOS; the editor's interface depends on the installed program.<\/p>\n
          1. Open a Shell. Inspect the file before changing it:<\/li><\/ol>\n
            Type S:Startup-Sequence<\/code><\/pre>\n
            1. Create a uniquely named backup on the boot volume, then check that it exists. Choose another suffix if this backup already exists:<\/li><\/ol>\n
              Copy S:Startup-Sequence TO S:Startup-Sequence.before-test CLONE\nList S:Startup-Sequence.before-test<\/code><\/pre>\n
              1. Keep a separate copy of that backup on transfer media as well. For S:User-Startup<\/code>, substitute that filename in both places; if it does not exist, record that instead of treating it as a failed backup.<\/li>
              2. On AmigaOS 3.x<\/strong>, open the file with Ed S:Startup-Sequence<\/code>. Move to the suspect command and put a semicolon (;<\/code>) at the start of that line only<\/strong>. To save and exit ED, press Esc<\/strong>, type X<\/code>, then Return. To abandon the edit, use Esc<\/strong>, Q<\/code>, Return and confirm quitting without saving.<\/li>
              3. On ApolloOS<\/strong>, open its supplied text editor and use Open<\/strong> to select S:Startup-Sequence<\/code>. Make the one-line change and save as plain text to the same path. If its Ed<\/code> is the compatible editor, the command above is also usable; do not assume another editor has ED's keyboard shortcuts.<\/li>
              4. Reopen or Type<\/code> the file to check the saved line. Leave IF<\/code>\/ENDIF<\/code> structure and unrelated ROM\/bootloader commands intact.<\/li>
              5. Finish writes, restart and repeat the original failing action. If the change did not help, restore the backup:<\/li><\/ol>\n
                Copy S:Startup-Sequence.before-test TO S:Startup-Sequence CLONE<\/code><\/pre>\n
                1. If the edited system no longer starts, enter Early Startup and choose Boot With No Startup-Sequence<\/strong>, then run the restore command there. If booting from another disk, S:<\/code> points to that<\/strong> disk: identify the affected volume with Info<\/code> and use its explicit path, such as AffectedSystem:S\/Startup-Sequence<\/code>, for both source and destination. Replace AffectedSystem:<\/code> with its actual volume name.<\/li><\/ol>\n
                  Use the same backup\/edit\/restore method for an existing launcher or WHDLoad script, substituting its real path. Do not edit Amiga startup files in a word processor that adds formatting.<\/p>\n<\/span>\n
                  \ud83c\udff7\ufe0f Change one icon tooltype and undo it<\/h3>\n
                  1. Locate the application's icon. For the AmigaOS RTG driver, open SYS:Devs \u2192 Monitors<\/strong> and locate vampiregfx<\/strong>. For WHDLoad, use the game's launch icon<\/strong>.<\/li>
                  2. Back up its .info<\/code> file to a new filename outside the Monitors drawer<\/strong> before editing. Run MakeDir SYS:V4-backups<\/code> only if that drawer does not already exist, then copy the file. Choose a different backup suffix if this copy already exists:<\/li><\/ol>\n
                    Copy DEVS:Monitors\/vampiregfx.info TO SYS:V4-backups\/vampiregfx.info.before-test CLONE<\/code><\/pre>\n
                    1. Select the original icon once. On Workbench choose Icons \u2192 Information<\/strong>; on an ApolloOS desktop use the corresponding icon Information<\/strong> action. Open its tooltype list.<\/li>
                    2. Record the current entry. Add or edit only the named tooltype, without adding a duplicate. In the standard tooltype convention, an entry enclosed in parentheses is disabled: (NoAutoVec)<\/code> is not the same as NoAutoVec<\/code>.<\/li>
                    3. Save, close and relaunch the application. Reboot for a monitor-driver tooltype. Run the same test that previously failed.<\/li>
                    4. If it does not help, restore the prior entry or copy the backed-up .info<\/code> over the original, then relaunch\/reboot as appropriate. For the example above: Copy SYS:V4-backups\/vampiregfx.info.before-test TO DEVS:Monitors\/vampiregfx.info CLONE<\/code>.<\/li><\/ol>\n
                      Only use a tooltype documented by that particular program. An icon-information window does not make AmigaOS driver options valid for ApolloOS.<\/p>\n
                      \ud83d\udee1\ufe0f Preserve a recovery point<\/h3>\n
                      1. Record the configuration<\/a>: board model, memory, core filename, OS release, drivers and any expansion board.<\/li>
                      2. Make a whole-device backup image<\/strong> of the original CF, including the partition map and areas outside ordinary files. Use the backup procedure below<\/a>.<\/li>
                      3. Store the backup on another drive. Keep a separate copy of irreplaceable personal files where they can still be read.<\/li>
                      4. Keep the previous core and its matching driver and utility packages.<\/li>
                      5. Record whether the working setup uses the core's bundled ROM, a ROM mapped from disk, or a separately flashed ROM. For a separately flashed ROM, preserve the exact licensed source ROM file and the compatible flasher outside the V4, along with a spare CF that can boot the core's bundled ROM. A CF backup alone does not preserve a separately flashed ROM.<\/li>
                      6. Photograph the first error or failed boot screen before changing anything.<\/li><\/ol>\n
                        \u26a0\ufe0f If the card produces read errors:<\/strong> stop ordinary write tests and repairs. Keep the card, recovery image and error log. An image made with unreadable sectors is a partial recovery, not a verified backup.<\/p>\n<\/span>\n
                        \ud83d\udcbe CF cards and disk images<\/h2>\n
                        \ud83d\uded1 The host asks to initialise, format or repair the CF<\/h3>\n
                        Cancel the prompt.<\/strong> Windows normally cannot mount Amiga filesystems such as FFS, SFS or PFS3, and it may not recognise an Amiga RDB partition layout.<\/p>\n
                        1. Windows:<\/strong> cancel Format\/Initialise. macOS:<\/strong> choose Ignore<\/strong> in the unreadable-disk dialogue. Linux:<\/strong> close the unsupported-filesystem dialogue; do not accept a format\/repair offer.<\/li>
                        2. Follow the physical-device and capacity check for your host<\/a>. A detected physical card and a mountable volume are different things.<\/li>
                        3. If you have just written an image, open the writer's result\/log and require both write and verification success.<\/li>
                        4. To inspect the actual Amiga layout, back up the CF<\/a> and use the read-only RDB procedure<\/a> on an image copy.<\/li><\/ol>\n
                          \u26d4 Do not do any of the following to make the warning disappear:<\/strong><\/p>\n
